Music, mental disorder and emotional reception behavior

Gebhardt, Stefan & von Georgi, Richard

Abstract

Objective: Current research based on neurobiological findings provides

evidence for direct effects of music on the modulation of activation and

arousal. In the current study associations between the functional-recep-

tive use of music in everyday life on specific diagnostic groups of mental

disorders (according to the international classification of disorders, ICD-

10) were ascertained.

Methods: n=55 patients with addictive, schizophrenic, affective, neu-

rotic, and personality disorders (mean age 46 ± 14 years) of the Depart-

ment of Psychiatry and Psychotherapy of the University of Marburg/

Germany were included. The „Inventory for the assessment of Activa-

tion- and Arousalmodulation through Music“ (IAAM) was used to ascer-

tain the dimensions: Relaxation (RX), Cognitive Problem Solving (CP),

Reduction of negative Activation (RA), Fun Seeking (FS) and Arousal

Modulation (AM). Data were compared by ONEWAY analysis with

healthy control populations (n=187 students aged age 21 ± 3 years;

n=106 adults aged 43 ± 6 years).

Results: Significant differences were found with respect to diagnostic

groups and the control samples for the parameter RX (p<0.001), CP

(p<0.001), RA (p<0.001), FS (p<0.001), but not for AM. Further analy-

ses with respect to possible sex and age influences results in specific pat-

terns of the use music for emotion modulation in these fife scales

compared to the patient groups (p<0,001).

Discussion: The results suggest that patients with mental disorders

clearly tend to use more music for RA, RX and CP than control samples,

while healthy young persons tend to an increased positive stimulation.

However, positive stimulation is reduced especially in patients with per-

sonality disorders, where a strong RA by music is apparent. In particular

patients with addictive disorders, but also patients with schizophrenic

disorders show for all parameters high scores. In contrast, patients with

affective disorders demonstrate a lack of RA.

Conclusion: This first study provides preliminary hints, that the func-

tional-receptive use of music for the modulation of emotional activation

processes in patients with mental disorders is quantifiable. Further stud-

ies with respect to findings in different mental disorders on the basis of

this approach are warranted.

1. Introduction

The high impact of music on psyche and therefore on mental disorders is

unchallenged. Since ancient times music is an integral part of cure pro-

cesses in many cultures. Therefore, music reception should play a crucial

role within the dynamic of mental disorders, and hence for the course and

therapy of mental disorders (Sheratt, Thornton & Hatton, 2004; Gebhardt

& von Georgi, 2007). Especially on the basis of a multitude of recent

neurophysiological studies demonstrating impacts of music – not only on

the cortex – but also directly on basic emotional systems (Panksepp &

Bernatzky, 2002), one should expect differences of modulation of emo-

tions by use of music between different patient groups with mental disor-

ders. This assumption goes in line with recent studies explaining the

conscious everyday life use of music by means of a neurobiological

approach (von Georgi, Grant, von Georgi & Gebhardt, 2006a).

Investigating the current state of research on the impact of music on psy-

chological dimensions three separate categories have to be differentiated:

studies on (a) active and (b) receptive/passive music therapy and (c) on

the functional-receptive, everyday life use of music, as an interactional

process. The latter being the concern of the current study refers to the fact

that listening to music is mostly preceded by an active action which is

associated with more or less conscious individual-specific aims of action

(Leontyev, 1978; Frese & Sabini, 1985; Hacker, 1994), which are based

on learned behavior and personality dispositions. In the following some

aspects of these three categories will be addressed with respect to healthy

subjects and patients suffering from non-psychiatric or mental disorders.

Studies on healthy individuals provide evidence for links between music

preferences and personality dimensions (Rentfrow & Gosling, 2003; von

Georgi, Grant, von Georgi & Gebhardt, 2006b) or between types of

music (e.g. excitative versus sedative) and aroused feelings or physiolog-

ical responses of heart rate, respiration and blood pressure (Iwanaga &

Moroki, 1999, Blood & Zatorre, 2001). A reduction of anxiety levels was

found in healthy subjects exposed to their preferred musical selections

(Salamon et al., 2003). In a meta-analysis a significant decrease of

arousal due to stress was found by use of music alone or music assisted

relaxation techniques (Pelletier, 2004). It also could be shown that in the

presence of music, the cortisol level ceases to increase after a stressor

(Khalfa et al., 2003). Hereby the association of stress coping strategies

and the use of music seems to be influenced by socio-psychological

covariables (von Georgi, König & Gebhardt, in press).

Music in non-psychiatric diseases has been studied predominantly on a

therapeutic basis. For example, active music therapy is effective on

motor, affective and behavioral functions, e.g. in patients with Parkin-

son's disease (Pacchetti et al., 2000). In patients undergoing hemodialysis

active music therapy may be applied as a method of nursing intervention

contributing the improvement of quality life by reducing anxiety and

depression (Kim, Lee & Sok, 2006). But also merely the reception of

music induces relaxation before and after surgery or diagnostic proce-

dures, helping to save sedative drugs, what results in a positive effect for

the course of the illness (Mok & Wong, 2003; Good et al., 2005; Sied-

liecki & Good, 2006). Cancer patients are as well interested in receptive

music therapy and their interest and preference were associated with neg-

ative affect, anxiety, age, perceived intervention-specific benefits, barri-

ers and self-efficacy (Burns et al., 2005). Further, pleasant music

contributes to pain relief, where the personal preference seems to be an

influential factor (Lai, 2004; Mitchell & MacDonald, 2006; Roy, Peretz

& Rainville, 2007). One study found more power and less pain, depres-

sion and disability by use of music in patients with chronic non-malig-

nant pain than the control group (Siedliecki & Good 2006).

Studies on patients with mental disorders revealed significant effects of

active and receptive music therapy. Koger, Chapin & Bronts (1999)

found in a meta-analysis of 21 empirical studies on subjects suffering

from symptoms of dementia an overall significant effect of music ther-

apy, while another meta-analysis of 5 studies displayed inconclusive

results, possibly due to poor methodological quality of the examined

studies (Vink, Birks, Bruinsma, Scholten, 2004). Meta-analyses of quan-

titative studies on music therapy in children and adolescents with autism

(9 studies; Whipple, 2004) or psychopathogical symptoms (11 studies;

Gold, Voracek & Wilgram, 2004), however with methodological deficits,

showed overall efficacy of both active and receptive music therapy with-

out significant differences (Whipple, 2004), in particular for patients with

behavioral and developmental disorders (Gold, Voracek & Wilgram,

2004). Further, results from a metananalysis of 19 studies with a total of

543 patients suffering from psychotic symptoms indicate a significant

reducing effect on symptoms of psychosis irrespective whether active or

passive music therapy was applied (Silverman, 2003), whereas according

to a more recent meta-analysis of 4 studies with merely moderate meth-

odological quality active music therapy may be more affective in patients

with psychosis (Gold, Heldal, Dahle & Wigram, 2005).

Apart from such studies evaluating active or passive music therapy,

almost no systematic scientific data on the functional-receptive use of

music in everyday life of individuals suffering from mental disorders

exist. For example, current psychobiological models of addictive disor-

ders are focused on the capability of drugs to cause a pathological exploi-

tation of the neural rewarding system often combined with the use of

music, e.g. by means of rave parties (Nencini, 2002), and with aggressive

behaviors (Chen, Miller, Grube & Waiters, 2006). According to a study

on tobacco smoking in a group of 152 high school and college students a

higher preference for music associated with anxiety and depressed mood

among smokers was found (Posluszna, Burtowy & Palusinski, 2004).

Altogether, music studies on patients concentrate predominantly on

active or in part passive (i.e. receptive) music therapy, but have ignored

largely examining the active everyday life use of music, which is for

example mirrored by preference behavior. Studies on the functional-

receptive effect of music were restricted predominantly to “ad hoc” sur-

veys, the situation-dependent rating of presented music examples (see

Gembris, 2002) or to more general effects, e.g. stress reduction effects

(see Pelletier, 2004). No differentiation of music effects on different

diagnostic groups of patients with mental disorders within one represen-

tative general psychiatric patient population has been carried out so far.

However, especially this music reception behavior might have a crucial

impact on psychological dimensions highlighting the need for a compre-

hensive assessment of patient needs and preferences prior to intervention

(see also Burns et al., 2005). The investigation of variables influencing

the use of music in patients with mental disorders should not only lead to

a better insight in psychopathological processes, but also have an impor-

tant impact on the development of empirically based music therapy con-

cepts.

One reason might be found in the fact that no reliable and valid psycho-

metric instrument assessing the way of music reception and the use of

music in everyday life has existed so far. Therefore, the “Inventory for

the assessment of Activation- and Arousalmodulation through Music”

(IAAM), has been developed in order to ascertain quantitatively the basic

dimensions of the functional utilization of music for the modulation of

emotional activation processes (von Georgi, Abou Seif, Grant & Beck-

mann, 2004; von Georgi, Grand, Adjormand & Gebhardt, 2005; von

Georgi, Grant, von Georgi & Gebhardt, 2006a; von Georgi, 2007). Theo-

retically the basic dimensions of using music in everyday life are inte-

grated into the neurophysiological model of Gray & McNaughton

(2003), what enables the connection of different theoretical and empirical

approaches as well as the linkage to neurophysiological research results

(von Georgi, Grant, von Georgi & Gebhardt, 2006a). First empirical data

clearly show the development of personality-dependant strategies to

modulate negative and positive emotions. These strategies can be mea-

sured and have direct positive influence on physical well-being (von

Georgi, Grant, von Georgi & Gebhardt, 2006a, 200b; von Georgi, Cimbal

& von Georgi, in press).

Thus, in the current study for the first time possible differences of func-

tional-receptive effects of music of patients suffering from mental disor-

ders categorized according to diagnostic groups to the International

Classification of Disorders (ICD-10; Dilling, Mombour & Schmidt 2004)

were assessed.

2. Method

STUDY SAMPLE: n=55 patients (32 female; mean age 46 ± 14 years) consecutively admit-

ted at the Department of Psychiatry and Psychotherapy of the Philipps-

University of Marburg/Germany were categorized according to the diag-

nostic groups of ICD-10 with mental and behavioural disorders due to

psychoactive substance use (F1; n=7), schizophrenia, schizotypal and

delusional disorders (F2; n=11), mood affective disorders (F3; n=21),

neurotic, stress-related and somatoform disorders (F4; n=8) and disorders

of adult personality and behavior (F6; n=8), while subjects of other ICD-

10 diagnostic groups (e.g. organic, including symptomatic, mental disor-

ders (F0); behavioral syndromes associated with physiological distur-

bances and physical factors (F5); mental retardation (F7); disorders of

psychological development (F8)) were missing in this sample. The mean

global functioning according to the Global Assessment of Functioning

Scale (GAF; scale range 0 – 100; American Psychiatric Association,

1987) of the study sample was 51 ± 11.

CONTROL SAMPLES: (a) n=181 students (128 female; mean age 21 ± 3 years) of the first

semester medicine (von Georgi, Cimbal & von Georgi, in press). (b) 106

adult persons (53 male; mean age 43 ± 6 years), recruited by chance out

of selected middle-class companies, insurance institution as well as club

associations (Lahn-Dill-Kreis, Kreis Gießen). Inclusion criteria of this

control sample were a minimum age of 30 years and the patient's agree-

ment to participate in the study. The majority was employed, married and

had at least one child (von Georgi, König & Gebhardt, in press).

ASSESSMENT: „Inventory for the assessment of Activation- and Arousalmodulation

through Music“ (IAAM) showing high reliability and validity (von

Georgi, Grant, von Georgi & Gebhardt, 2006a; von Georgi, 2007) mea-

sured the situation-dependent everyday life use of music according to the

parameters Relaxation (RX), Cognitive Problem Solving (CP), Reduc-

tion of negative Activation (RA), Fun Seeking (FS) and Arousal Modula-

tion (AM). Further, the „Selbstkonzept-Inventar“ (SKI) (von Georgi &

Beckmann, 2004) was used, its results are not demonstrated in the current

composition.

STATISTICS: First, using univariate analysis of variance (ONEWAY analysis) the three

samples were studies for significant differences in mean values. To

exclude, that possible group differences do not display the result of influ-

ences of age or sex, all IAAM scales were corrected for the influence of

these variables and using the unstandardized residuals ONEWAY analy-

sis was carried out again. In a third step, in order to get differential find-

ings with respect to the strength of use of music within the patient

sample, possible differences of mean values considering diagnostic

groups of the ICD-10 were assessed.

3. Results

Reliability assessment of the different scales (Cronbach’s Alpha) resulted

in sufficient reliability coefficients of the scales RX, CP, RA, FS and AM

for the student control sample (0.91; 0.91; 0.90; 0.86; 0.84), the adult

control sample (0.92; 0.91; 0.90; 0.87; 0.86) as well as the patient sample

(0.90; 0.89; 0.92; 0.88; 0.86). Thus, also in the current study there is good

evidence for the reliability of these scales.

Legend: RX: relaxation; CP: cognitive problem solving; RA: reduc-tion of negative activation; FS: fun seeking; AM: arousal modula-tion; Model: raw data (RD) vs. by age and sex adjusted uncorrected residuals (UR); M: mean; SD: standard deviation; ONEWAY: results of the one factorial variance analyses; F: F-value; DF: degrees of freedom; p: significance level

The first analyses of possible mean differences without considering an

impact of sex and age result in significant differences (p<0.001) between

the control samples and the clinical sample for all IAAM scales except

for the AM scale (table 1). In particular significant increased mean values

of the clinical patient group were found for the RX, CP and RA scales,

which assess a modulation of negative emotional states. For FS the gen-

eral findings indicate that especially students attempt to modulate posi-

tive emotions by music. It must be emphasized, that these results may be

hampered by the influence of sex and age differences. The following

multiple regression analyses displayed except for the scale AM signifi-

cant associations with age and sex of the pooled samples (see table 2).

Legend: RX: relaxation; CP: cognitive problem solving; RA: reduc-tion of negative activation; FS: fun seeking; AM: arousal modula-tion; R: multiple regression coefficient; F: F-value; DF: degrees of freedom; p: significance level; .p(ß): significance level of the single ß-coefficients for age and sex

Hereby, in the scale RX sex differences were predominant, in contrast to

age differences in the case of RA. These results indicate, that relaxation

by music is more used by females, whereas the reduction of negative

emotional activation by music is mostly used by young persons. How-

ever, the scales CP and FS were found to be sex- and age-dependent.

These strategies are mostly used by young females. Due to these results

all scale values where corrected with respect to sex and age calculating

unstandardized residuals. Table 1 displays descriptive statistical data as

well as the results of ONEWAY analyses: it is recognizable, that except

for the scale FS both uncorrected (RD) and unstandardized residual (UR)

data lead to comparable results. Age and sex are therefore important

covariables, however not influencing the existing group differences. One

exception is the scale FS: the non-significant effect of uncorrected resid-

uals provides evidence, that age and sex are influencing variables, which

contaminate the differences between the three samples. It can be seen in

table 1 that the uncorrected mean of the student sample compared to the

following analyses.

IAAM scale means based on unstandardized residuals

Figure 1 shows mean scores of the unstandardized residuals of the scales

for the three samples. As in table 1 it can be found, that the clinical

patient group use by far more often and pronounced music for modula-

tion of negative somatic (RX), cognitive (CP) and activational (RA)

emotional states compared to the control samples, except for the FS scale

assessing positive stimulation through music. Thus, the question arises

concerning possible differences among the different diagnostic groups of

present mental disorders, because the increased scores of the patient sam-

ple do not necessarily display a general behavioral tendency of all

patients.

and somatoform disorders (n=8); F6: disorders of adult personal-ity and behavior (n=8)); RX: relaxation; CP: cognitive problem solving; RA: reduction of negative activation; FS: fun seeking; AM: arousal modulation (Scheffe-Test: *: p≤0.05).

Figure 2 shows the results of ONEWAY analyses and the unstandardized

residual mean scores for the IAAM scales among each diagnostic group.

With the exception of the scale AM highly significant effects of the

groups were observed. In particular the increased values of the diagnostic

group of “mental and behavioral disorders due to psychoactive substance

abuse” (F1) and „schizophrenia, schizotypical and delusional disorders”

(F2) were conspicuous with the first group showing predominantly

clearly increased scores on the scales RX, CP and RA. Similarly, the

slightly increased RA score in the case of „disorders of adult personality

and behavior“ (F6) on the one hand and the decreased score of the scale

FS in this group on the other hand are impressing.

Altogether, the results suggest already, despite of limited data, that not

just the total study sample of patients suffering from mental disorders is

characterized by an increased emotional modulation by music. In fact,

according to the current state of the first analyses there are rather specific

patient groups which seem to prefer influencing their affects using music,

whereas other patient groups (mood (affective) disorders, neurotic,

stress-related and somatoform disorders) seem to be modest compared to

control samples.

4. Discussion

The results of this first study suggest that some patients with mental dis-

orders clearly tend to use music more for reduction of negative emotional

activation (RA), cognitive problem solving (CP) and somatic relaxation

(RX) compared to the control samples, which show a higher positive

stimulation, in particular at young age (student sample). This finding

indicates that healthy young persons might use music mostly in order to

stimulate themselves positively, whereas patients with mental disorders

might exhibit impairments in this skill. It has to be clarified in further

studies – possibly for each diagnosis separately – whether these impair-

ments play an additional role in the development of mental disorders or

whether they represent an epiphenomenon. Salamon et al. (2003) believe,

that within the general population, many people do not have an adequate

self-understanding regarding what genre of music would best relax them.

Thus, especially these individuals might be at higher risk for failure of a

positive functional modulation of emotional activation processes. Music

might therefore merely be used for influencing the psychic state as best

as possible, e.g. by reduction of negative activation or might even be part

of dysfunctional behavior strengthening psychopathological processes.

Anyway, it is likely that these possible impairments are involved in both

causal and maintaining factors of mental disorder leading in a dialectic

manner towards a pathological process such as a vicious circle. Of

course, not in each individual suffering from a mental disorder music has

a substantial impact on pathological processes – some patients have

never been listened very much to music in their life at all; however,

music represents a valid correlate of the personal affective-cognitive-

activational way of managing the efforts, every subject is exposed, and

should therefore be of high interest for research. Psychotherapeutic expe-

rience suggest that, particularly in patients who deny music effects,

music therapeutic approaches or comparably therapeutic strategies com-

bining cognitive, affective and action-related dimensions (e.g. somatic

psychotherapy) are indicated.

In particular, positive stimulation is reduced in patients with personality

disorders (F6), where a strong reduction of negative activation by use of

music is apparent, probably in order to overcome with strong emotions or

aggression. For example, what concerns patients suffering from border-

line personality disorder, it is well known, that their efforts to downregu-

late high affective activation levels has got a high impact in

psychopathology of these patients; the use of music is therefore a compa-

rably functional skill in order to cope with such tension states and is even

sometimes recommended as therapeutic intervention to avoid more dys-

functional behavior such as suicidal behavior. Additionally it could be

shown, that persons with a high preference for heavy metal represent on

the one hand indeed a personality that is allied with salient personality

characteristics (psychoticism, sensation seeking), but on the other hand

are characterized by a high psychological and somatic health (von

Georgi, Cimbal & von Georgi, 2006a; von Georgi, König & Gebhardt,

2007). Compared to the present clinical sample, healthy persons with a

high preference for hard music show a marked ability to stimulate them-

selves positively by means of music. This finding supports the present

interpretation.

Mostly in patients suffering from addictive disorders (F1), but also

schizophreniform disorders (F2) show high scores for all parameters (see

figure). Accordingly, active listening to music may have a high functional

impact on emotional modulation for some diagnostic groups of mental

disorders – in case of addictive disorders possibly an addictive use of

music in order to aim for a maximum effect on all parameters.

In contrast, patients diagnosed with affective disorders (F3) demonstrate

a lack of RA. Because the study sample did not contain manic patients,

one therapeutic implication is that depressed patients may be instructed

to use music for reduction of negative affects, e.g. aggressions. Patients

suffering from neurotic, stress-related and somatoform disorders (F4)

seem to be mostly comparable with the healthy student sample, however

by far a lower score for FS. Or in other words, though patients suffering

from neurotic, stress-related and somatoform disorders (F4) have nearly

the same level of positive stimulation as the control group of on age 30

years, their levels of the remaining modulation strategies correspond

more to the students group, meaning that there seems to be a disquilibra-

tion, which might refer to impaired psychosocial and therefore agedepen-

dent development stages. Finally, in this study the arousal modulation by

means of music, focusing predominantly on concentration processes

appears to have a lower impact (von Georgi, 2007; von Georgi, Cimbal &

von Georgi in press).

Following the development of modern brain research methods (PET,

firm) it could be demonstrated, that music with its corresponding charac-

teristics (e.g. tuning, dynamics, harmony, timbre etc.) addresses different

cortical and basal structures of the central nervous system, which refer to

positive or negative affects and emotions (Blood, et al., 1999; Blood &

Zatorre, 2001; Tramo, 2001; Juslin & Sloboda, 2001; Panksepp & Ber-

natzky, 2002; Altenmüller et al., 2002; Kreutz et al., 2003). Especially the

finding, that a sudden autonom reaction on negative stimuli can take

place without any exact cortical representation (LeDoux, 2000), high-

lights the fact, that music is able to evoke and modulate emotional states

independent from higher central cognitive processes (Panksepp & Ber-

natzky, 2002; Winkielman & Berride, 2004). Hereby, musical stimuli

have been shown to activate specific pathways in several brain areas

associated with emotional behaviors and corresponding mental disorders,

such as the insular and cingulated cortex, hypothalamus, hippocampus,

amygdale, in ventral striatum, midbrain, orbitofrontal cortex and ventral

medial prefrontal cortex (Blood & Zatorre, 2001; Boso, Politi, Barale &

Enzo, 2006). These brain structures refer to reward/motivation, emotion

and arousal and are known to be active in response to survival-related

stimuli such as food, sex and drugs of abuse. While regions as the

amygdala or the ventromedial prefrontal cortex would be activated in

unpleasant states such as anxiety, music might be able to modulate this

activity and adjust the activity of additional structures known to cause

positive emotions, e.g. structures of the reward system. In addition,

according to neurochemical studies several biochemical mediators, such

as endorphins, endocannabinoids, dopamine, nitric oxide and neurotro-

phins may play a role in the musical experience (see Boso, Politi, Barale

& Enzo, 2006; Angelucci et al., 2007). Thus, there is a link of music with

biologically relevant stimuli via their common recruitment of brain cir-

cuitry involved in pleasure and reward (Blood & Zatorre, 2001).

The above interpretations should be handled with care due to the low

patient sample size of this present study. On the other hand this is the first

study within this field and it should lead to further hypotheses and empir-

ical based studies. However, data clearly show already at this time the

above described tendencies, which are from both a theoretical and a clin-

ical point of view easily comprehensible. These results are encouraging

for continuing the systematic investigation with greater patient samples

on the basis of this methodology.

Conclusion:

To our knowledge, this is the first study providing preliminary hints, that

the functional-receptive use of music for the modulation of emotional

activation processes in patients with mental disorders is quantifiable. In

addition, for the first time differences between the use of music for mod-

ulation of emotions among diagnostic groups of patients suffering from

mental disorders have been assessed. Overall these results suggest that

patients with mental disorders display decreased positive stimulation by

use of music compared to (especially young) healthy probands. This

finding indicates that healthy (young) persons might use music mostly in

order to stimulate themselves positively, whereas (older) patients with

mental disorders might exhibit impairments in this skill. On the other

hand some clinical groups are showing a clear accentuation of the use of

music to modulate negative emotional states. This may be an indication

for the fact that music is used to try to reduce these emotional states.

However, it is still an open question whether this affective behavior of

reducing illness related negative psychological and somatic states really

works. Perhaps it may also lead to a possible enhancement of the existing

disorder.

Music probably represents a valid individual affective-cognitive-activa-

tional correlate and should therefore be of high interest for research. Fur-

ther studies on music reception behavior differentiating according to the

diagnoses of mental disorders on the basis of this approach are urgently

warranted. The aim is to continue to reveal associations between specific

music reception behavior, personality dimensions and diagnoses of men-

tal disorders. In the long-term these findings should result in the develop-

ment of corresponding empirically based diagnostic, preventive and

therapeutic strategies with respect to the use of music. Finally, empiric

evaluation studies of active and receptive music therapy are required.
