Additionally, the prevalence and levels of embitterment among the participants were assessed. This cross-sectional methodological study included 575 participants. Following a rigorous forward-backward translation process, the PTED-21 was adapted into Turkish. Reliability was assessed using Cronbach's alpha and split-half reliability coefficients. To evaluate construct validity and identify the factor structure, exploratory factor analysis (EFA) was performed using principal component analysis with varimax rotation. Reliability analysis yielded a Cronbach's alpha of 0.960 and a Spearman–Brown coefficient of 0.961. The Kaiser–Meyer–Olkin value was 0.958, and Bartlett's test of sphericity was statistically significant <i>(p &lt; 0.001)</i>. Factor analysis revealed that the Turkish PTED-21 consists of a three-factor structure, explaining 67.49% of the total variance. The Turkish version of the PTED-21 is a valid and reliable instrument for assessing embitterment. Its clinical application may significantly enhance the diagnostic assessment of embitterment in Turkish-speaking populations.</p>\u0000 </div>","PeriodicalId":10460,"journal":{"name":"Clinical psychology & psychotherapy","volume":"33 4","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148419359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Study 2, parallel process latent growth curve models indicated that changes in perceived stress accounted for substantial proportions of the intervention effects on anxiety and depression. Random intercept cross-lagged panel models further suggested that perceived stress functioned as a temporally prior process particularly for subsequent depression, whereas the temporal association with anxiety was more bidirectional.

Indicators of low feasibility may be a high dropout rate, a low attendance rate and low treatment satisfaction, which threaten the validity of clinical research studies. Given the severity and chronicity of bipolar disorder and its impact on psychosocial functioning, effective treatments are needed to alleviate depressive and manic symptoms. The study evaluated the feasibility and preliminary treatment effects of a novel disorder-specific metacognitive group training for bipolar disorder (MCT-Bipolar), which targets cognitive biases specific to depressive and manic episodes while also incorporating mindfulness techniques. Forty-eight outpatients with bipolar disorder I and II participated in the training conducted by a clinical psychologist for eight consecutive weeks in groups of six to 10 people. Inclusion criteria were euthymia or mild or moderate depressive symptoms. Predictors of dropout and attendance rates were analysed using regression methods, and secondary exploratory analyses examined changes in various efficacy indicators between baseline, 1 week after training and 6 months after training using linear mixed models. In total, 10 participants (20.8%) dropped out, while completers attended an average of six out of eight sessions. Treatment satisfaction of the completers was high. Linear mixed models revealed an increase in mindfulness from baseline to follow-up. Results on psychosocial functioning showed an increase from baseline to post-training, though this effect disappeared at the 6-month follow-up. Findings support the feasibility of MCT-Bipolar and suggest potential benefits for mindfulness and short-term psychosocial functioning.
