Mood Spectrum Self Report (MOODS-SR) is an innovative instrument to assess mood spectrum symptomatology. This may provide a better way of conceptualizing the psychopathology of affective disorders.

Psychometric evaluation of the Swedish adaptation of MOODS-SR, lifetime version.

Patients with affective disorders were recruited from outpatient services at Sahlgrenska University Hospital. Patients and a convenience sample of healthy controls were offered to fill in the MOODS-SR. This is a preliminary analysis of the collected data; data from more participants will be presented at the conference. Internal consistency was evaluated using Cronbach's α and the mean score on subdomains compared between groups using a Student's t-test in STATA.

September 2014, 22 patients with affective disorders and 67 controls had answered the MOODS-SR. The age (mean ± sd) of patients was 39.8 ± 11.8 years compared to 40.7 ± 12.7 years of controls (p=0.79). The patient and the control group consisted of females by 73% and 69% respectively (p=0.33). Cronbach's α was 0.89 in patients and 0.90 in controls regarding the total score on the 7 subdomains; i) mood depressive, ii) mood manic, iii) energy depressive, iv) energy manic, v) cognition depressive, vi) cognition manic, vii) rhythmicity. The mean scores on the 7 subdomains were all statistically significantly higher among patients (p value<0.001).

The Swedish MOODS-SR, lifetime version, has good internal consistency among both patients with affective disorders and controls. Furthermore, the patient group displayed consistently higher mean scores than the control group in all subdomains.
