170 hospitalised patients (96 schizophrenic, 71 depressive, and 3 manic) were examined using the German version of the CPRS. Based on factor analytical results four subscales (‘manic syndrome’, ‘schizophrenic syndrome’, ‘depressive syndrome’, and ‘side-effects’) and two second-order scales (‘manic-depressive syndrome’ and ‘schizophrenic syndrome’) were constructed. The first three subscales show a good reliability. The fourth subscale (‘side-effects’) has an unsufficient internal consistency, mainly due to the small number of items (6). The two subscales ‘schizophrenic syndrome’ and ‘depressive syndrome’ and the two second-order scales can differentiate very well between schizophrenic and depressive syndromes. The validity of the first and fourth subscale could not be examined in this study.

The interrater reliability of the AMP system and the Comprehensive Psychiatric Rating Scale (CPRS) was compared in a sample of 30 hospitalized schizophrenic or depressive patients. The CPRS proved to have on average a slightly higher reliability on both the level of items and primary scales. The reliability of the secondary scales was nearly identical.

The EPOCH Measure of Adolescent Well-being measures five positive indicators of the well-being of adolescents: engagement, perseverance, optimism, connectedness and happiness. This five-factor structure along with other indicators of validity and reliability were supported for the original English version and the Chinese version. In this study, we tested the psychometric properties of the Swedish version of the EPOCH with a sample (n = 846) of Swedish high school adolescents aged 16–21 years (Mage = 18, SD = .85). The participants answered a questionnaire containing the EPOCH, Coping Self-Efficacy Scale, and 21-item Depression, Anxiety, and Stress Scale (DASS-21). A confirmatory factor analysis supported a the five-factor, inter-correlated model. The internal consistency was good for all the EPOCH subscales (Cronbach’s α = .76–.88, McDonald’s ω = .77 –.88). The criterion validity was established by replicating correlations between the five EPOCH subscales and positive (coping self-efficacy) and negative (DASS-21) aspects of well-being. This study shows that the Swedish version of the EPOCH is suitable for assessing multiple dimensions of adolescent well-being.

The interrater reliability of the German version of the CPRS was examined in 30 patients (18 schizophrenic, 11 depressive and 1 manic). All patients were examined by the same two raters. The agreement of 55 out of 65 items was determined using the kappa coefficient. Kappa was calculated concerning symptom present/not present and difference ≤ 2/difference > 2. 49 or 54 items show a moderate to excellent agreement. Items based on self-rating have a better interrater reliability than items based on the rating of the psychiatrists. The interrater reliability of the syndromes was calculated, using the rank correlation coefficient. The agreement concerning the 4 primary and the 2 second-order factors is high or excellent. The good results show the usefulness of the CPRS for the assessment of psychopathological findings.

Humanistic and positive psychology have had a contentious past. Initially, positive psychology researchers have distanced themselves from humanistic psychology, proceeding to build an array of differentiated constructs relevant to an empirical study of well-being. Twenty years on, it is now generally acknowledged that humanistic psychology is the theoretical predecessor of positive psychology in terms of holistic growth theories. In this theoretical review, we aim to show how Carl Rogers’ organismic valuing process (OVP) theory can serve as a holistic framework for individual positive psychological research findings and theories and how positive psychology, in turn, provides empirical support for this meta-theoretical framework. An important motivation for considering personal growth as a process that integrates various aspects of well-being is theoretical integration, which can help us better understand how well-being develops in individuals across the lifespan. Some theoretical and practical implications of incorporating OVP theory into well-being research are also suggested.
