(56.9%) and 93 boys (43.1 boys). Age distributions range from 14 to 18; the average age is 15.50. Distributions by grade level are as follows: 80 9th graders (37%), 77 10th graders (35.6%), and 59 11th graders (27.4%). 3.2 Process During the process of data collection from participants, it was indicated that voluntariness was essential in the process, and informed consents were taken in writing, and personal information was not included in the process by indicating that their information would not be used outside of research within the scope of personal data confidentiality. For the application, support was received from the school psychological counselor, the application was carried out in a classroom environment as a group. 3.3 Measures Personal Information Form; it consists of two parts. First, the study contains information towards determining adolescents’ gender, age and class levels, as well as academic achievement level, parental work status, family income level, parent marital status, and whether they received psychological support in the last 1 year. The second part includes adolescents’ loss experiences to determine their losses, and the adolescents were asked to state their losses. In this section, adolescents’ loss experiences were evaluated using frequency and percentage values and presented in descriptive findings. Grief Scale was developed to identify physical, emotional, intellectual and behavioral changes that occurred after the loss of a loved one or ones. The Scale is a 5-type Likert scale, consisting of a total of 35 items and four sub-dimensions. These sub-dimensions include physical, cognitive, behavioral and emotional responses shown in the face of grief. Cronbach alpha coefficient calculated to determine the internal consistency of the scale is .96. Retest reliability coefficient was found to be .84 (Balcı-Çelik, 2006). Five-Dimensional Well-Being Scale for Adolescents (EPOCH) assesses adolescents’ well-being in terms of characteristics such as engagement, perseverance, optimism, connectedness and happiness. Compliance index values calculated as a result of the scale’s confirmatory factor analysis were found to be at an acceptable level (x² = 381.29, sd = 160, RMSEA = .074, NFI = .96, NNFI =.98, CFI = .98, IFI = .98, RFI = .96 and SRMR = .052). Factor loads of items on a scale range from .37 to .84. Internal consistency coefficients for the sub-dimensions of the scale range from .72 to .88. The internal consistency coefficient of the total score of the scale was calculated as .95 (Demirci & Ekşi, 2015). Social Support Assessment Scale for Children and Adolescents (C-SSAS) was developed by Dubow and Ullman (1989; 1991) to assess children and adolescents’ perceptions on the social support received from their families, friends (close friends and classmates) and teachers. Cronbach alpha reliability coefficient for the entire scale was found to be .93; test re-test reliability coefficient for the entire scale was found to be .49 (p< 0.01). The two-half reliability of the scale (Guttman) was determined as .82 (Gökler, 2007). 3.4 Data Analyses Prior to conducting the structural equation modeling, preliminary analyses were performed to examine the correlations between variables, descriptive statistics, and analysis assumptions. Normality was checked using skewness and kurtosis scores and their cut-off values (Curran, West & Finch, 1996; Kline, 2015). Pearson correlation analysis was then performed to investigate the association between study variables. After conducting the preliminary analyses, the structural equation model was used to examine the mediator role of the social support in the association between grief and well-being among adolescents. Common data-model fit statistics and their cut-off scores were used to assess goodness of fit for structural model: comparative fit index (CFI) and Tucker-Lewis index (TLI) ≥ .90 = adequate and ≥ .95 = close data-model fit; root mean square error of approximation (RMSEA) ≤ .08 = adequate, and ≤ .05 = good data-model fit (Hooper, Coughlan & Mullen, 2008; Kline, 2015). Findings from the structural model were also interpreted using the standardized path coefficients (β) and squared-multiple correlations (R2 ): 01–.059 = small, .06–.139 = moderate, and ≥ .14 = large (Cohen, 1988). All analyses were performed using SPSS version 25 and AMOS version 24. 4. Results This study tested a model developed to examine the role of social support in the relationship between adolescents’ level of loss and grief and their psychological well-being. The findings of the study are as follows, ies.ccsenet.org International Education Studies Vol. 13, No. 12; 2020 32 respectively; the demographic findings of the participants, results of descriptive statistics and correlations, and finally the results of proposed model tested. 4.1 The Participants’ Demographic Characteristics When the findings of the participants’ demographic characteristics are examined; participants evaluated their academic achievements, and 63 adolescents indicated their academic achievement at low level (27.3%), 103 of them in moderate level (44.6%), and 50 adolescents in high level (28.2%). In addition, in the findings of adolescents’ families, it was indicated that 95 of them had low family income (42.9%), 106 of them had moderate level of income (47%), and 15 of them had high level of income (11%).
