BackgroundThere is a lack of questionnaires assessing the motivation of inpatients to scrutinize occupational stresses and deal with them as part of their psychotherapeutic treatment. Work-related stress contributes significantly to the development of mental disorders. Vocational reintegration is an outcome criterion for the success of vocational rehabilitation. Patients are often not motivated for dealing with occupational stresses during inpatient medical rehabilitation. Therefore it is necessary to assess patient motivation at the beginning of treatment, in order to assign them to specific interventions, e. g. promoting motivation.MethodA questionnaire (Fragebogen zur berufsbezogenen Therapiemotivation -- FBTM) consisting of 84 items was developed, based on published questionnaires for psychotherapy motivation. 283 psychosomatic rehabilitation inpatients were administered the FBTM, subsequently analyzed by item and factor analyses. Based on a second sample (n = 282) confirmatory factor analyses and validation of the questionnaire were executed.ResultsItem and factor analyses revealed a four factor structure. 24 items constituted the subscales that could be described as "intention to change", "wish for pension", "negative treatment expectations" and "active coping". Reliability (Cronbach's Alpha) was satisfactory with coefficients between 0.69 and 0.87, and only low correlations could be found between the four subscales. Correlations with other measures were most pronounced for the subscale "intention to change". Some significant but low correlations could be reported between the FBTM and a standardized questionnaire of psychotherapy motivation (FMP). Confirmatory factor analyses of a second sample (n = 282) confirmed the original four factors. First evidence of sensitivity could be observed in a sample of patients who took part in an intervention promoting work-related therapy motivation during psychosomatic inpatient rehabilitation.ConclusionsThe FBTM is a reliable and valid instrument assessing work-related therapy motivation of inpatients, as a relevant therapeutic measure in psychosomatic rehabilitation. Further validation, especially the analysis of predictive validity is desirable.
