SummaryAim: To examine the psychosocial and environmental distress resulting from the 2010 eruptionof the Merapi volcano and explore the experience of living in an environment damaged by avolcanic eruption.Background: Natural disasters cause psychosocial responses in survivors. While volcanic erup-tions are an example of a natural disaster, little is currently known about the psychosocialimpact on survivors. Volcanic eruptions also cause degradation of the environment, which is
linked to environmental distress. However, little is currently known of this phenomenon.Design: An explanatory mixed method study.Methods: The research will be divided into three phases. The first phase will involve instrumentmodification, translation and testing. The second phase will involve a survey to a larger sampleusing the modified and tested questionnaire. The third phase will involve the collection ofPlease cite this article in press as: Warsini, S., et al. Psychosocial and environmental distress resulting from a volcaniceruption: Study protocol.

ntroduction
here has been a proliferation of disasters in the lastew years including natural disasters, disasters associatedith climate-change, and human-made disasters (Simpson,eissbecker, & Sephton, 2011). One massive natural disas-
er that occurred in Indonesia in the last three years ishe eruption of Mount Merapi in the Yogyakarta region,ndonesia. This mountain is located on Java Island, on theorderlines of Sleman District, Yogyakarta Special Regionrovince and Magelang, Klaten, and Boyolali Districts, Cen-ral Java Province. In the last eruption of Mount Merapi,n October 26 and November 5, 2010, 386 people died, andver two hundred people were injured, mostly due to severeurns. The eruption forced more than 300,000 people fromour districts in Yogyakarta and Central Java to be evacu-ted to cramped emergency shelters (Surono et al., 2012).his disaster inflicted a financial loss up to US$400 million,esulted in the loss of a large area of fertile land, andmpacted many settlements (Wartatmo, 2010). This paperescribes a study protocol to explore the psychosocial dis-ress related to the volcanic eruption and the emotionalistress resulting from living in an environment damaged byhe volcano.
ackground
any scientists have conducted research on the psychosocialmpacts of natural disaster. However, research related to thesychosocial impact specifically related to volcanic erup-ions and the environmental distress resulting from theseisasters is limited.
From the research conducted to date, it is evidenthat a volcanic eruption causes several psychosocial prob-ems including depression and posttraumatic stress disorderPTSD) (Araki, Nakane, Ohta, & Kawasaki, 1998; Goto,ilson, Kahana, & Slane, 2006; Howard et al., 1999; Ohta
t al., 2003). Goto et al.’s (2006) research concluded thathe loss of goods and uncertainty related to the futurelays an important role in causing these symptoms. Mean-hile, survivors who undergo several relocations are more
ikely to suffer from psychosocial distress compared tohose who only experience it once. Some demographicata such as age, marital status, social economy, edu-ation, and duration of living around the mountain areelated highly to the occurrence of psychosocial prob-ems (Goto et al., 2006). This could be because eruptionso not occur over a short period of time like earth-uakes, and because of the frequency of eruptions by

ome active volcanoes which may burden the peopleiving around it and finally result in psychosocial prob-ems.

People living in damaged environments may feel dis-ressed by the changes they see. Studied to date by twoesearch teams (Connor, Albrecht, Higginbotham, Freeman,
Smith, 2004; Higginbotham, Connor, Albrecht, Freeman, Agho, 2007), the studies support Albrecht’s claim (2002),
hat people can feel ‘homesick’ at home when the land-cape around them is significantly changed or damaged.lbrecht defined the term ‘solastalgia’ that he proposed ishe distress or sadness a person feels when his or her homenvironment is negatively changed. Solastalgia may resultn people feeling unfamiliar in their own environment, evenhough they continue to live where they always have. Thisistinguishes solastalgia from nostalgia; that is, survivorsxperience a type of homesickness even though they haveot moved from their homes (Warsini, Mills, & Usher, 2014).lthough Albrecht (2005) hypothesized that solastalgia mayesult from the damage resulting from natural disasters, toate this has not been tested. The research that has beeneported about volcanic eruptions mostly discusses the sur-ivors’ responses to the disaster or to living in a relocationrea or a shelter. However, the fact that eruptions can have aasting impact on the environment and even trigger a secondisaster, has received little attention to date. In additiono that, research on the role of place attachment and itsmpact on the survivors’ experience in overcoming the envi-onmental change caused by an eruption, has not previouslyccurred.

he aims of the research are to measure the psychosocialnd environmental distress resulting from the 2010 eruptionf the Merapi volcano and explore the experience of livingn an environment damaged by a volcanic eruption.
Specifically, we aimed to answer the following researchuestions:
. How has the eruption of Merapi affected the psychosocialhealth of people who live near the volcano?
. What is the level of environmental distress caused byliving in an environment damaged by a volcanic eruption?
. What is the experience of living in the shadow of a very-active volcano and how does this impact on the mentalhealth of the local community?

depth of information that cannot be examined quantita-tively, through a qualitative approach. Mixed method isconsidered appropriate to gain information about the psy-chosocial and environmental distress experienced by peoplewho live nearby the Merapi volcanic mountain. Integrationof the data, an important aspect of all well designed mixedmethod studies, will occur between the second and thirdphase of the study, where the results of phase two will drivethe questions in phase three, and in the final analysis whereall data will be merged to answer the research questions(Creswell & Plano Clark, 2011, p. 234).
Participants and setting
The research will be conducted in the Merapi community inIndonesia, primarily in Cangkringan and Pakem sub districtsof Jogjakarta province. Cangkringan sub district experi-enced the worst damage and the most deaths from theMerapi eruption in 2010 while Pakem sub district experi-enced several eruptions before the 2010 eruption but wasnot damaged in the 2010 eruption.
In the first phase of the research (quantitative), aconvenience sample will initially be used to test theappropriateness of the tools with a representative groupof participants (n = 30), and to perform a test retest(n = 80—110) of the tools. Once this has been completed,a larger stratified sample will be recruited to completethe questionnaire (n = 350). Systematic stratified samplingmeans the population will be divided into at least two differ-ent subgroups (or strata) that share similar characteristics(Triola, 2009). The advantages of systematic stratified samp-ling are ensuring of sampling representativeness and gaingreater accuracy (Schofield, 2003, pp. 181—182). A furthersample will target people not affected by the 2010 Merapieruption, living in areas not destroyed by the eruption, toget a baseline level of distress for the local population.
A group of 350 survivors will be recruited to participatein this survey from a total population of about 13,000 peo-ple residing in the area. A final sample of 350 is consideredsufficiently powered to answer the research questions. Thetarget sample size of 175 people from Cangkringan and 175from Pakem enables us to detect a mean difference of 1 unitin the EDS scale (assumed standard deviation (SD) 3 based onHigginbotham et al., 2007) with a power in excess of 80% andan overall level of significance of 0.05. Systematic stratifiedsampling will be used to recruit participants. The researcherwill stratify samples by sub-district (Cangkringan and Pakem)then chose two villages from each sub-district. Further clas-sification, according to gender and age groups (elderly andyoung adult) will be performed. Residents of every fifthhouse in the selected sub-districts will be approached toparticipate. The adult resident whose next birthday is clos-est will be invited to participate if they meet the inclusioncriteria.
In the third phase of the study, a smaller sampledrawn from the same individuals in the second phase ofthe research will be undertaken using purposive sampling.

Respondents with high and low EDS and IES-R scores fromthe quantitative result will be sought to help explain thephenomenon further (Creswell & Plano Clark, 2011, p. 235).The purpose of this sample is to enhance understanding

f environmental distress and to understand the impact ofhe event in each group, and to determine if the groupsre typical or average in relation to their psychosocialesponse. Interviews will be continued until data saturationccurs, that is, where the same information is being heardStreubert, 2011). We expect that a sample of about 15—20ill be required to achieve this goal.
nclusion criteriahe respondents must meet the following inclusion criteria:
. lived in the area all of their life;
. experienced the eruption of Merapi in 2010 and now livein an area with environmental damage (study cohort);
. experienced the eruption before 2010 and now live inan area with no environmental damage (comparisoncohort);
. adult, over 18 years old;
. willing to consent to the study;
. able to communicate their experiences to theresearcher;
xclusion criteriahe exclusion criteria are as follows:
. evidence of a severe mental illness/disturbance;
. difficulty hearing or speaking;
ata collection
easures demographic section will be included in the survey. Par-icipants will be asked to complete a number of questionsuch as age, gender, education level, living arrangements,mployment, pre-disaster experiences, and post-disasterxperiences including losses experienced. The survey willlso have an area where the participant can indicate theirillingness to be interviewed.
The Environmental Distress Scale (EDS) is a 117 itemcale developed by Higginbotham et al. (2007). The EDSas designed to measure how people appraise the envi-
onmental degradation produced by activities of open-cutining industries. However, it has been suggested that this
ool can be adapted to measure distress arising in otherontexts such as climate change, and natural disaster. Thecale has been tested with populations in Upper Hunter Val-ey, Australia and demonstrated strong internal consistencyCronbach’s alpha = 0.79—0.96) and test retest reliabilityICC = 0.67—0.73) (Higginbotham et al., 2007). The tool willnitially undergo modification in preparation for use in a vol-ano setting as while Higginbotham et al. (2007) suggest theool may be useful for natural disasters. It has not previouslyeen used in this context. Translation and back translationrior to testing and dissemination will also be undertaken.
The Impact of Event Scale—–Revised is a self-report mea-ure of current subjective distress in response to a specificraumatic event and contains 22 items. The original scale,

he research will be divided into three phases over two yearssee Fig. 1).
hase 1he goal in this phase is to modify the Environmental Dis-ress Scale (EDS) (Higginbotham et al., 2007) to ensure itsppropriateness for use in Indonesia with residents of theerapi volcano area. An initial scoping exercise will assist
he researcher to understand the need for amendment ofhe tool. After the EDS scale content is modified it wille translated into Bahasa Indonesia and then back trans-ated as required by an authenticated person (Jones, Lee,hillips, Zhang, & Jaceldo, 2001). The IES-R scale will alsoe translated using the same process. Brislin’s (1986, p. 159)ranslation model requires three steps: (1) forward trans-ation of the tools into Bahasa and Jawa checked by twoilingual experts; (2) back translation (into English) by twoifferent bilingual experts; and (3) comparison of the orig-nal English version by two back-translation experts (Chent al., 2011; Jones et al., 2001). The aim of the translationrocess is to produce a version of the tool that is culturallynd setting specific yet as close as possible to the originalersion (Chen et al., 2011). The survey, which will includeoth measurement tools and a demographic section, willhen be pilot tested (sample n = 30), and followed by a test-

hase 2he second phase is the conduct of the correlational surveyesearch. As many as 350 people living in the Cangkringannd Pakem sub district will be recruited to the study usingystematic stratified sampling. The researcher will stratifyamples by villages (hamlets), and then sample householdsystematically within villages/hamlets. The researcher willisit every fifth house in every lane in a village until theample for that area is fulfilled. The proportion of respon-ents according to age (adult and elderly), and sex (femalend male), are expected to be similar in both groups (Pakemnd Cangkringan sub district).
Data collection will be performed through researcher-ssisted interviews for elderly respondents who may find itifficult to fill out the tools themselves. Otherwise the toolill be self-administered. The survey tool is expected to
ake participants about 20 min to complete. See Fig. 2 forhe data collection procedure.
hase 3 descriptive exploratory qualitative study will be under-aken. The qualitative phase will aim to explore and explainhe particular characteristics and experiences of differentroups of respondents. For example, this phase will attempto unravel why some respondents score higher or lower onhe subscales of the survey tool, and why some respondentsave average score. The sample for the qualitative data col-ection phase will be chosen purposively from representativeespondents with the lowest and the highest scores on theDS and IES-R scores and who have indicated their willing-ess to be interviewed. Further, the information gatheredn the initial phase of the study will be used to develop theuestions to be explored in the qualitative phase. Interviewsill continue until the same information is being heard. Wexpect this to occur after interviewing approximately 15—20articipants.

The interviews will beconducted in Bahasa Indonesia, the transcriptions will be inBahasa Indonesia and the data analysis conducted in BahasaIndonesia. Approximately two transcripts will also be tran-scribed to English to allow for cross checking of analysis.
Data analysis
All quantitative data will be analyzed using the Statisti-cal Package for the Social Sciences (SPSS) version 21. Datafrom psychometric testing (phase 1) for both scales will beassessed using intra class correlation coefficients or concord-ance correlation coefficients. Internal consistency will bemeasured using Cronbach’s alpha test. Cronbach alpha andIntra Class Correlation scores of more than 0.6 will be set inthis research.
Data from the second phase (large survey) will be sub-jected to descriptive statistics and inferential statisticsconducted as required. Descriptive statistics will be used togain information about percentages, mean standard devia-tions and median values of EDS, IES-R score and demographicdata related to respondents such as age, and gender. Bivari-ate tests will be conducted using parametric tests such asun-paired t tests or non-parametric Mann—Whitney tests tocompare EDS and IES-R results among groups to addressthe main research questions. Further, bivariate statistics
