Primary | Medication Adherence Rating Scale | The Medication Adherence Rating Scale was developed by Thompson et al. (2000). It evaluates the adherence behavior and attitude of the patient within the previous week. There are 10 close-ended questions (yes/no answers) in the questionnaire. | for two study groups at baseline(T0) and after 4 session interim analysis (T1;9-12 weeks) and 8 session after intervention (T2;21-28 weeks). | |
Secondary | Schedule for the Assessment of Insight, SAI | The Schedule of Assessment of Insight (SAI) measures multiple dimensions of insight, including compliance with treatment, recognition of illness, re-labeling of psychotic phenomena, and awareness of changes in mental functioning and psychosocial consequences of the illness.The maximum score of the SAI is 14, with higher SAI scores indicating greater insight. The Cronbach alpha for the SAI was 0.96, and inter-rater reliability (r) between the two research psychiatrists was .92 in the present study. | for two study groups at baseline(T0) and after 4 session interim analysis(T1;9-12 weeks) and 8 session after intervention(T2;21-28 weeks). | |
Secondary | Positive and Negative Syndrome Scale, PANSS | PANSS assessed the severity of psychotic symptoms in terms of three subscales, including positive symptoms (hallucinations,delusional beliefs, and 30-item 7point Likert scale (from 1-'Absent' to 7-'Extremely'). | for two study groups at baseline(T0) and after 4 session interim analysis(T1;9-12 weeks) and 8 session after intervention(T2;21-28 weeks). | |
Secondary | Self-Appraisal of Illness Questionnaire, SAIQ | The Self-Appraisal of Illness Questionnaire (SAIQ) was used to assess patients' insight into their illness.The need for treatment and presence/outcome of illness subscales of SAIQ have been used as brief screening instruments for schizophrenic patients who may be at risk for treatment noncompliance. Lower SAIQ subscale scores indicate reduced awareness of the psychiatric illness. This scale is a self reporting instrument composed of 17 items in which participants are asked to rate the extent to which they agreed with each statement by using a 4-point Likert scale ranging from 0 (ie, "do not agree at all") to 3 (ie, "agree completely").
The internal consistency of the scale was 0.867, and the retest reliability was 0.82. |
