Abstract:Objective: To investigate the cross‐cultural feasibility of a new scale for assessing dysfunctional working models of self and others, and to evaluate its discriminative power.
Method: Schizophrenic patients (N=351), non‐psychotic patients (N=86) and non‐clinical subjects (N=511) collected in 10 centres completed the DWM‐S. Current psychopathology was assessed by means of the BPRS.
Results: Alpha coefficients were high in all samples. Mean scores on the DWM‐S appeared to be comparable in all countries, suggesting cross‐national generalizability. No significant correlation was found with sex, age, levels of psychopathology and duration of illness. Discriminant analyses showed that more than 70% of the schizophrenic patients are correctly classified.
Conclusion: The DWM‐S is an easily administered self‐report instrument which allows to pinpoint internal dysfunctional working models of self and others in various types of patients. It is a useful tool for case conceptualization, especially when psychotherapeutic interventions are part of the treatment programme.
