Öğe I am Learning to Protect Myself with Mika: A Teacher-based Child Sexual Abuse Prevention Program in Turkey(Sage Publications Inc, 2022) Kiziltepe, Rukiye; Eslek, Duygu; Irmak, Turkan Yilmaz; Gungor, DuyguThis study aimed to explore the effectiveness of a teacher-based child sexual abuse prevention program entitled I am learning to protect myself with Mika. The sample consisted of 290 children, their parents, and their classroom teachers. The participants were randomly assigned to intervention (n = 137) or wait-list comparison groups (n = 153) by classroom. The age of the children ranged from 46 to 71 months (M = 58.99, SD = 6.64). The prevention program was a 5-week program that consisted of five modules, including emotional awareness, good touch-bad touch, and body safety rules. To investigate the effectiveness of the prevention program, a latent Markov analysis was conducted. A three-class solution was identified as the best model: Status-1 (self-protecting group), Status-2 (risky secret keepers), and Status-3 (risk group). Following the intervention, members of the two at-risk groups (Statuses 2 and 3) were more likely to move into the Status-1 group than were those participants who had not received the intervention (wait-list comparison). Self-protection skills were analyzed using a 2 x 2 ANOVA with repeated measures. The increase in self-protection skills was greater for participants in the intervention group than for those in the wait-list comparison group from pre-test to post-test. Two-month follow-up analysis showed that gain in knowledge and skills was maintained. This program should be considered as a potential approach to meeting the need for child sexual abuse preventive efforts in Turkish preschool curriculum.Öğe I'm Learning to Protect Myself with Mika: Efficacy of Sexual Abuse Prevention Program(Turkish Psychologists Assoc, 2018) Irmak, Turkan Yilmaz; Kiziltepe, Rukiye; Aksel, Seyda; Gungor, Duygu; Eslek, DuyguThe aim of this study was to evaluate the effectiveness of a child sexual abuse prevention program for the preschool children. Two hundred participants who were five years old children and their parents were included in the study. 47% (n = 82) of the participants were male while 53% (n = 93) of them were female. In total, the results of 175 students (education group = 102, control group = 73) who met the inclusion criteria were analyzed. All children were administered Sexual Abuse Knowledge Form and Self-Protection Skills Form before and after the implementation. Parents were surveyed by using Parental Evaluation Form. Sexual prevention program which was named as "I am learning to protect myself with Mika" was implemented in six pre-schools. Latent Markov analyses showed that, model with three status fits better to the data and transition probabilities of this model revealed significant improvements in the education group. Status-1 was named as self-protecting group. Status-2 was named as group who knows to be touched is wrong but keeps it as a secret. Status-3 was named as a risk group who does not know to be touched is wrong and keeps it as a secret. After the education, members of the Status-1 group in the education and control group remained in the same status; while in the education group, 70% of Status-2 group and 35% of Status-3 group moved to Status-1. However, in the control group, only 15% of Status-2 members moved to Status-1. The results, limitations and strengths of the study were discussed in the light of the literature.Öğe Measurement Equivalence across Gender with Mean and Covariance Structure of Five Factor Personality Inventory for Adolescent Sample(Turkish Education Assoc, 2013) Korkmaz, Mediha; Somer, Oya; Gungor, DuyguThe purpose of the present study was to investigate the measurement equivalence for boys and girls' comparison groups in the mean and covariance structure (MACS) methods by using the data obtained from the Five Factor Personality Inventory (5FPI). The participants were 490 (63.1% girl, 36.9% boy, mean age 16.59 standard deviation .841) students from 3 high schools (2 public,1 private) in Izmir. The Cronbach's alpha coefficients for five factors were found in the range of .78 (conscientiousness) and .93 (neuroticism). Exploratory factor analysis pointed big five for adolescents like adults. 17 sub dimensions were indicators and 5 factors were latent variables of our measurement model. Measurement equivalence across genders was tested with five nested mean and covariance structure models. As a result all configural, weak, partial strong and strict models provided acceptable fits to the data.Öğe Model Selection in Measurement Equivalence Studies with Latent Class Analysis(Hacettepe Univ, 2015) Gungor, Duygu; Korkmaz, Mediha; Sazak, Hakan SavasPurpose of this study is to investigate measurement equivalence with latent class analysis in different conditions. Latent class analysis is an alternative method when both observed and latent variables are discrete, or continuous but assumptions like normal distribution, homogeneity, unidimensionality are violated. Within the study 28 different conditions were simulated by changing; sample size, number of items, inequivalence type, number of inequivalent items. BIC, CAIC, AIC and AIC3 are used for model selection. In general, for all information criteria, increasing the sample size induced the true decision rate. Number of items did not cause any alteration in true decision rates. In scale level analysis true decision rates increase parallel with the number of inequivalent items. Also when there is inequivalence both in slope and intercept parameters, more true decisions are taken with respect to the case when there is inequivalence only in intercept parameter. In conclusion BIC and CAIC tend to select false negative, AIC tends to select false positive models whereas AIC3 seems to be more consistent.Öğe Multi-Group Latent Class Analysis and Measurement Equivalence(Turkish Psychologists Assoc, 2013) Gungor, Duygu; Korkmaz, Mediha; Somer, OyaSocial and behavioral research relies heavily on group comparison. Empirical demonstration of measurement equivalence is necessary when the attributes are compared. Latent class models are used when attributes are conceptualized as having discrete distributions and when discrete observed variables are used to estimate those distributions. This study illustrates the measurement equivalence in multi-group latent class analysis. Heterogeneous model imposes the same number of latent classes on two or more groups without imposing between-group parameter constraints. Homogeneous model is obtained by constraining the between-group conditional probabilities of the heterogeneous model equal. Measurement equivalence is established by demonstrating that the homogenous model fits the data as good as, if not better than, the heterogeneous model. Otherwise, the analysis moves to the exploratory mode to identify the offending equality constraints. The resultant model, if any, is called partial homogenous model. Using the Love Capacity dimension of Values in Action Inventory, the measurement invariance for latent class analysis is illustrated with a dataset involving 496 female and 237 male college students. A two-class model is chosen to represent both gender groups. Homogenous model was found to be the best fitting model. There was evidence for the equality of conditional probabilities between the groups, however, the equality constraint on unconditional probabilities was not supported, which led to the conclusion that the latent classes have the same meaning in both of the gender groups, i.e., measurement equivalence, but that the prevalence rates are gender specific.Öğe Prevalence of non-suicidal self-injury and distinct groups of self-injurers in a community sample of adolescents(Springer Heidelberg, 2015) Somer, Oya; Bildik, Tezan; Kabukcu-Basay, Burge; Gungor, Duygu; Basay, Omer; Farmer, Richard F.Adolescence is an important developmental period for the first onset of non-suicidal self-injury (NSSI), a behavior known to be associated with elevated suicide risk. Little is currently known, however, about NSSI among adolescents. The primary objectives of this research were to establish the prevalence of non-suicidal self-injury (NSSI) in a representative sample of Turkish high school students and to identify and describe distinct subgroups of self-injurers. A total of 1656 of 1676 eligible students (98.8 % participation rate) from 18 schools were surveyed during the 2010-2011 academic year. Questionnaires were administered that assessed prior engagement in a variety of self-injurious behaviors, current psychiatric symptoms, suicide-related risk factors, and participation in health-risk behaviors. Latent class analysis (LCA) methods were used to identify distinct groups of self-injurers. Almost one-third of the sample (N = 519) endorsed some previous engagement in NSSI behaviors. In LCA analyses restricted to youth with prior histories of NSSI, four distinct classes were identified characterized by: (1) low rates of NSSI behaviors (29 %); (2) high rates of self-battery (32 %); (3) high rates of self-cutting (19 %); and (4) high rates of multiple NSSI behaviors (19 %). These classes were further distinguished by current psychiatric symptoms, suicide risk factors, and other health-risk behaviors. Findings from the present study indicate that NSSI is a common form of behavior among adolescent youth. There is, however, considerable heterogeneity among those with NSSI histories, with about 40 % at particularly high risk for ongoing distress, future acts of intentional self-harm, and suicidal behavior.Öğe Prevalence of non-suicidal self-injury and distinct groups of self-injurers in a community sample of adolescents(Springer Heidelberg, 2015) Somer, Oya; Bildik, Tezan; Kabukcu-Basay, Burge; Gungor, Duygu; Basay, Omer; Farmer, Richard F.Adolescence is an important developmental period for the first onset of non-suicidal self-injury (NSSI), a behavior known to be associated with elevated suicide risk.
