From: Collaborative community based care for people and their families living with schizophrenia in India: protocol for a randomised controlled trial

1. Quantitative: (using a combination of programmed palmtops and paper and pencil methods)    Measured at:
Primary Outcome Interviewee Outcome assessment scale description 0 month 6 months 12 months
Symptoms Person with schizophrenia Positive and Negative Syndrome Scale (PANSS). The PANSS has 30 items to record current psychopathology on 3 domains- positive symptoms, negative symptoms and general psychopathology; each item rated on 1-7 scale thus having a total score range of 30-210. X   X
Disability Primary caregivers Indian Disability Evaluation and Assessment Scale (IDEAS). For the IDEAS evaluation, the participant is assessed on 4 domains- Self Care, Interpersonal Activities, Communication and Understanding and Work. The scale generates a global score of 0-20 with increasing scores indicating more severe disabilities X X X
Secondary outcomes
Stigma and discrimination Person with schizophrenia Discrimination and Stigma Scale (DISC). The version to be used is based on DISC-12, but was adapted for the study. The revised version has 30 items in total, all rated on a 4 point Likert scale ranging from 'not at all' to 'a lot'. X   X
   There are 20 items in the Negative Discrimination Subscale plus 1 new negative discrimination item generated for the trial, 4 items on anticipated discrimination, 1 item relating to efforts of overcoming stigma and discrimination and 4 items for recording experiences of positive discrimination.    
Internalized stigma   The Internalized Stigma of Mental Illness (ISMI) scale is designed to measure the subjective experience of internalized stigma and consists of 5 subscales. For the study, the 'Alienation' subscale was chosen. It consists of 6 items which are scored on a 4-point Likert scale ranging from 'strongly disagree' to 'strongly agree'. X   X
Willingness to disclose illness   An item on willingness to disclose mental illness rated on a 5-point Likert scale ranging from 'very uncomfortable' to 'very comfortable'. X   X
Quality of life   Euroqol EQ-5D that has a descriptive assessment of 5 domains: mobility, self-care, usual activities, pain/discomfort, anxiety/depression. Each domain is coded as level 1, 2 or 3 and combined into a 5 digit code together with a summary visual analogue scale assessment of quality of life score 0-100. X   X
Subjective rating of adherence with antipsychotic medication   Adherence rating tool with 5 ordinal ratings to describe a range of adherence (from non adherent- fully adherent) X X X
Knowledge of and attitudes towards illness Primary caregiver(s) Knowledge about Schizophrenia Interview (KASI). There are 6 domains of understanding that are assessed; the maximum score for each domain being 4. X   X
The family burden of caring   The Burden Assessment Schedule (BAS). The BAS is scored on 40 items with a maximum score of 120; the minimum score can be less than 40 as some questions can be rated as 'not applicable'. X   X
Costs of illness   Cost of Illness Schedule (CIS) X X X
Adherence with antipsychotic medication   Adherence rating tool with 5 ordinal ratings ranging from non- adherent to fully adherent supplemented by audit of actual medicine use over last 2 months that is extrapolated to the previous 6 month period X X X
