The main focus of this study was to investigate links between the diathesis-stress hypotheses of the quadripartite model and the helplessness-hopelessness theory of depression. Simultaneously the study tested the psychometric properties of the Turkish version of the Learned Helplessness Scale (LHS). To this end, the LHS was initially administered…

In a six-wave longitudinal study with two cohorts (660 adolescents and 630 young adults), this study investigated the longitudinal stability of the Beck Depression Inventory II (BDI-II) using the Trait-State-Occasion (TSO) model. The results revealed that the full TSO model was the best fitting representation of the depression measured by the…

This study investigated the relationship between dimensions of perfectionism and anxiety sensitivity. The study group is composed by 398 (211 female; 187 male) students who were studying at the pedagogical formation certificate program at Mugla Sitki Kocman University.

The study investigated the relationship between childhood trauma and types of attachment and the predictive role of childhood trauma on types of attachment. The sample was composed of 911 (492 female; 419 male) university students at Mugla Sitki Kocman University, in Turkey. Data were collected using the brief screening version of the Childhood…

According to Blatt (2004; Blatt & Luyten, 2009) and others (e.g., Beck, Epstein, Harrison, & Emery, 1983), establishing positive self-definition and mature relatedness to others represent core lifespan developmental tasks. In a sample of emerging adults, this study examined the effects of the quality of one close friendship and changes in…

Depression and posttraumatic stress disorder (PTSD) are highly comorbid conditions that may arise following exposure to psychological trauma. This study examined their temporal sequencing and mutual influence using bivariate latent difference score structural equation modeling. Longitudinal data from 182 emergency room patients revealed level of…

The Beck Depression Inventory-II (BDI-II) is a frequently used scale for measuring depressive severity. BDI-II data (404 clinical; 695 nonclinical adults) were analyzed by means of confirmatory factor analysis to test whether the factor structure model with a somatic-affective and cognitive component of depression, formulated by Beck and…

Building upon earlier confirmatory factor analytic research that validated a second-order, three-factor structure of the Beck Depression Inventory for Canadian and Swedish nonclinical adolescents, this study tested the factorial structure of the Swedish version of the instrument separately for 559 males and 537 females, and tested its measurement…

Emphasis is placed on the use of empirically supported therapies in clinical practice as a manifestation of the scientist-practitioner approach. The predominant model used to provide empirical support for interventions uses groups of patients in randomised clinical trials in university settings. This model has severe limitations for the clinician.…
