The orthogonal-oblique bi-level model of the Outcome Questionnaire (OQ-45.2): Polish adaptation based on factor analysis.

UNLABELLED: AIM : The aim of this project was to conduct the cross-cultural factorial validation of the Outcome Questionnaire (OQ-45.2) using the Polish population. METHODS: Data were obtained from day-patients (n = 211), inpatients (n = 234), outpatients (n = 137) and non-patients (n = 426). Statistical analyses included: parallel analysis, exploratory factor analysis, confirmatory factor analysis, correlation analysis, criterion equivalence, clinical significance and reliable change index, and test-retest. RESULTS: Statistical analyses provided the strongest support for the bi-level model of the total score, five orthogonal (subscales specific for the Polish OQ, i.e. Social Conflicts and Addictive Behaviors; and original yet modified subscales, i.e. Symptom Distress, Interpersonal Relations, and Social Role), and two oblique factors (Somatization and Anxiety, Social Role 2). The psychometric properties of the Polish OQ were found to be adequate and similar to the original American OQ and its international adaptations. Specific for the Polish OQ cut-off scores for clinical significance were established. The role of cultural differences and the passage of time in the process of the cross-cultural validation were elaborated upon. CONCLUSIONS: The Polish version of the OQ 45-2 has been recognized as an instrument adequately measuring general functioning as well as specific areas of functioning of the individual (i.e. interpersonal relations; social role performance; social conflicts; symptom distress; somatization and anxiety; addictive behaviors). Results of this factorial analysis seem to be valuable for both clinicians using the OQ-45.2 and for creators of any psychotherapy outcome measure.

[The outcome of inpatient psychotherapy and previous psychotherapy duration]. / Wyniki psychoterapii w warunkach stacjonarnych a czas trwania wczesniejszej psychoterapii.

AIM: The previous psychotherapy duration was the main independent variable. METHOD: 301 patients successively reporting for inpatient treatment in the Clinic of Neurotic Disorders received questionnaires. 274 patients completed the treatment and returned all the tests and were divided into three groups: a) those without previous psychotherapy, b) those with the experience of previous short-term therapy, c) those with previous long-term psychotherapy. The following tools were used: Hopkins Symptom Checklist, Sense of Coherence, Questionnaire of Motivation, and Adjective Check List. RESULT: Previous psychotherapy duration discriminates symptoms, coherence, motivational factors, personality aspects, both in the beginning of psychotherapy and at the time of discharge from the hospital.

[Motivational factors in psychotherapy of eating disorders]. / Czynniki motywacyjne w psychoterapii zaburzen odzywiania sie.

AIM: We examined changes in general psychopathology during psychotherapy of patients with eating disorders. We were also interested in distinguishing motivational characteristics of completers and dropouts with anorexia and bulimia nervosa. METHOD: All subjects completed two self-descriptive measures: Motivational Inventory and Hopkins Symptoms Checklist (HSCL-72). Questionnaires were completed three times: during the qualification visit, at admission and two weeks before discharge. RESULTS: It was observed that general psychopathology among patients with anorexia nervosa and bulimia nervosa decreased. Comparing to completers with bulimia nervosa completers with anorexia nervosa had a higher level of activity factor before the treatment. Dropouts with anorexia nervosa differed from completers in decreased level of threat factor and activity factor. Completers with bulimia contrasted markedly with statistically meaningful decrease of the Body Mass Index. CONCLUSIONS: The efficacy of cognitive-behavioural-social psychotherapy of patients with eating disorders seems to be confirmed by large decrease of general psychopathology. Dropouts with anorexia seem to have poorer insight concerned with lower need of health activity.
