Brief Summary

This randomized controlled trial aimed to examine the effectiveness of a 10-session acceptance-based, insight-inducing medication adherence therapy (AIM-AT) program for recent-onset psychosis (in addition to usual care) over a 12-month follow-up (i.e., at immediate, 6-month, and 12-month post-intervention).

Detailed Description

Objectives: To evaluate the effectiveness of an Acceptance-based, Insight-inducing Medication Adherence Therapy (AIM_ AT) for recent-onset psychosis on patient outcomes over 12-month follow-up, when compared with a standardized psychoeducation group and routine care only.

Focus-group interviews will be performed on purposively selected participants to examine perceived benefits, satisfaction and limitations of the AIM_ AT.

Hypotheses: Compared with psychoeducation group and routine care only, the AIM_AT participants will indicate significantly greater improvements in patients' adherence to anti-psychotic medication and illness/treatment insight and other secondary outcomes (symptom severity, drug attitude, progress of recovery, psychosocial functioning, satisfaction with service, and re-hospitalization rate) at immediate post-intervention, and/or greater improvements in the above outcomes at 6- and 12-month follow-ups.

Design: A multi-center RCT with repeated-measures, three-arm design. Subjects: 126 Chinese patients with recent-onset psychosis ( \</= 5 years) randomly selected from four Integrated Community Centers for Mental Wellness and randomly assigned into three study groups.

Instruments/outcome measures: Frequency, length of re-hospitalizations, and total number of patients being hospitalized from clinic records over 5-6 months; valid questionnaires (ARS, ITAQ, DAI, QPR, PANSS, SLOF, CSQ-8) for medication adherence, illness/treatment insight, drug attitude, recovery, symptom severity, functioning, and service satisfaction accordingly. Focus group interviews will collect views on benefits and weaknesses of the AIM_AT.

Data analysis: Comparing the mean value changes of outcomes between groups across time on intention-to-treat basis, using Mixed Modeling/GEE-test; and content analysis of data from focus-group interviews and intervention sessions will be conducted.

Expected results: The findings can provide evidence of the effectiveness of AIM_ AT for early-stage psychosis in community mental healthcare on improving patients' medication adherence, mental condition and recovery, functioning, and service satisfaction.

Arm && Interventions

Group	Intervention	Description
Conventional Psychoeducation Group program (CPG)	TAU	Psychoeducation groups (12-18 members/group) will be led by one trained psychiatric nurse in each center experienced in psychiatric rehabilitation, and are guided by a validated group-intervention protocol based on the research team's and McFarlane et al.'s psychoeducation programs for psychosis. The psychoeducation program consists of 10 two-hour sessions, weekly/biweekly (similarly, 4-month duration) and is comprised of six components: introduction and goal-setting; basic understanding of psychosis and symptom and emotion self-care; education workshop of psychosis care, treatment and community support services; learning about self-care skills; establishing social support and effective coping skills; and skills practices, review and future plan.
Treatment-as-usual only (TAU)	TAU	Routine/Usual care only (control) group participants (and the two treatment groups) will receive usual community mental healthcare services. The main services provided by the four ICCMWs mainly include day-time occupational and living skills training workshops, family mutual support groups, public and mental health education, social and recreational services, supportive groups services on specific mental health problems, referrals to community psychiatric and social care services, and individual and family counseling service as needed. In addition, the center users will also receive community mental health services provided by public hospital and outpatient departments.
Acceptance-based, insight-inducing medication adherence therapy (AIM-AT)	TAU	Acceptance-based Insight-inducing and Medication Adherence Therapy (AIM_AT) consists of 10 weekly/biweekly, 2-hour sessions (4-months), based on the modified Kemp's model/manual of Adherence therapy and mindfulness-based psychoeducation program developed by the research team. The integrative AIM_AT program based on the principles of motivational-interviewing technique (MI) and mindfulness- and acceptance-based therapy, which have been tested in our previous controlled trials and increasingly been shown to reduce both positive and negative psychotic symptoms and ambivalent attitude towards medication adherence and inducing treatment/illness insight.

Primary Outcome Measures

Name	Time	Method
Insight and Treatment Attitude Questionnaire (ITAQ)	At 12 months post-intervention	The 10-item ITAQ was developed by McEvoy et al.(1989) to measure patients' insight and recognition of their illness and attitudes towards treatment/medication needs. Items are rated on 3-point Likert-scale (0= 'Not necessary to receive medication/treatment' to 2= 'Medication/treatment continued/required regularly')
Adherence Rating Scale	At 12 months post-intervention	Rating (by RA and checking against patient records and center staff) on the level of medication adherence on a 5-point Likert-scale (1-'total non-adherence'; 2-' poor adherence'; 3-'inadequate adherence'; 4-'fair adherence'; and 5-'good adherence') with excellent inter-rater reliability and content validity.

Secondary Outcome Measures

Name	Time	Method
Drug Attitude Inventory (DAI)	At 12 months post-intervention	The DAI is a 10-item self-report scale measuring one's attitude towards drug adherence (equally balanced for True/False items) and containing two subscales (subjective positive and subjective negative attitude).
Questionnaire about the Process of Recovery (QPR)	At 12 months post-intervention	The QPR (Chinese version) consists of 22 items and 3 subscales (Self-empowerment \[10-items\]; Effective interpersonal relationships \[6-items\]; Rebuilding life \[6-items\]), rating on a 5-point Likert-scale ('0= disagree strongly' to '4= agree strongly').
Frequency and length/duration of re-hospitalizations	At 12 months post-intervention	Frequency and length/duration of re-hospitalizations over past 5-6 months will be reported by participants at baseline and post-tests, and checked with their center records.
Positive and Negative Syndrome Scale (PANSS)	At 12 months post-intervention	Mental state/Symptom severity is assessed with the 30-item PANSS(Kay 1987) across three subscales (positive symptoms, negative symptoms and general psychopathology). The scale is rated on a 7-point Likert-scale (1-'absent' to 7-'extreme'), for symptom severity.
Specific Level of Functioning Scale (SLOF)	At 12 months post-intervention	Patient functioning is measured by the 43-item SLOF (Schneider and Struening, 1983) in terms of three domains: physical functioning/personal care (12 items), social functioning (14 items) and community living skills (17 items) of psychosis sufferers, on 5-point Likert-scales.
Eight-item Client Satisfaction Questionnaire (CSQ-8)	At 12 months post-intervention	The CSQ-8 is well-accepted valid questionnaire to evaluate service users' opinions/conclusions about services received/receiving. Items are rated on 4-point Likert-scale (1- 'very dissatisfied' to 4- 'very satisfied').
