Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants received a brief structured intervention of up to six individual 60-minute sessions informed by Barber et al.’s (1995) intervention for heavy drinkers and adapted for use with gamblers. FRCM-Gam is based on learning theory principles and teaches CSOs to respond to the problem behaviour in a way that both empowers the CSOs and provides incentives for the gambler to change by decreasing the advantages of engaging in the problem behaviour and increasing the advantages of behaving differently. The intervention involves five graded steps of responses designed to gradually increase motivation for the gambler to change. Step one involves preparing the CSO by providing information about gambling addiction and CBT, the FRCM-Gam approach and collecting information about the gambler’s gambling behaviour. Step two involves identifying the benefits the gambler gains from gambling and identifying incompatible and desired behaviours (contingency management) and the principles of operant conditioning and shaping taught. At step three CSOs are taught to use the principles of operant conditioning and shaping to respond to the gambler when they display signs of gambling, non-gambling, or desirable behaviours. At step four CSOs make an agreement with the gambler about when they will engage in incompatible or desirable behaviours. Step five looks for ways to involve others in the behavioural plan if previous steps have not been successful. The experimental intervention will be delivered by up to six individual 60-minute sessions over six to eight weeks via in-person or telehealth videocall. The intervention will be delivered by a mental health clinician with a master's degree in CBT (psychologist, social worker, or psychiatric nurse),

Behaviour
Comparator / control treatment
Standard care
Participants received a brief structured intervention of up to six individual 60-minute sessions covering three areas. The first component provided information about gambling addiction from a cognitive behavioural perspective. The second component involved information and strategies about how CSOs can protect themselves financially from gambling-related harm. The third component involved stress management using principles of behavioural activation. The standard care intervention will be delivered by up to six individual 60-minute sessions over six to eight weeks via in-person or telehealth videocall. The intervention will be delivered by a mental health clinician with a master's degree in CBT (psychologist, social worker, or psychiatric nurse),

In addition, to the primary clinical outcome, the following outcomes concerning the wellbeing of concerned significant others (CSO)s will be collected: Patient Health Questionnaire (PHQ-9;(Kroenke et al., 2001) is a measure of depression. The scale consists of nice items that correspond to Diagnostic and Statistical Manual of Mental Disorders (4th ed.;DSM-IV) Diagnostic Criterion A symptoms for major depressive disorder (American Psychiatric & American Psychiatric Association. Task Force on, 1994). Cronbach’s alpha coefficients have been reported as .86 to .89 (Kroenke et al., 2001).

Kessler Psychological Distress Scale (K10(Kessler et al., 2002) is a 10-item self-report scale developed to measure non-specific psychological distress. The K10 has high internal consistency and a Cronbach’s alpha of 0.84 (Kessler et al., 2002).

Qualitative semi-structured interviews with up to 10 participants who received the experimental intervention. The semi-structured interview protocol is as follows: Qualitative interview questions for FRCM-Gam study 1. Can you describe your overall experience with the program? 2. What aspects of the program did you find particularly helpful? 3. Can you describe any positive changes you experienced as a result of this program? 4. Did you have any concerns about applying any of the strategies taught in this program? 5. How easy or difficult was it to understand the principles and strategies taught in this program? 6. What, if anything, do you think could be done differently to make the program more effective or beneficial? 7. How relevant do you think this program is for family or friends who are concerned about a loved one’s heavy gambling? 8. Is there anything else you would like to add? We will use purposive sampling to intentionally recruit participants who were successful in motivating the gambler to enter treatment, and those who were not able to motivate the gambler to enter treatment. We will use maximum variation sampling to recruit a diverse range of relationships of the participant to the gambler to ensure we capture the voices of partners, parents, siblings, friends.

Eligibility
Key inclusion criteria
Study eligibility is based on the following inclusion criteria: (1) individuals 18 years of age or older, (2) living with a family member or friend who they believe has a gambling problem and was not currently seeking help. If not living with the gambler, participants are required to have regular contact with them (at least once a week). The individual with the gambling problem is not required to have been formally diagnosed with a gambling disorder; it is sufficient that the participant report presence of a gambling problem. Family members have been found to be able to report problem gambling behaviour in a reliable and valid manner (Hodgins & Makarchuk, 2003).
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Participants are excluded if: (1) risk of violence is identified, (2) the potential participant also has a gambling problem, (3) experiencing significant mental distress e.g., psychosis or suicidality so as not to be able to provide informed consent, (4) not proficient in speaking and reading English. (5) not having regular contact (at least once a week) with the gambler. An initial screening interview will be conducted by telephone. On passing the online and telephone screening, participants will be provided with an information and consent form. On receipt of their consent form, they will be randomised to the intervention or standard care.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation will be performed by an administrative staff member who was not involved with the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be blocked to increase the likelihood of equal group sizes, using a standard permutated block algorithm in which block sizes will be randomly chosen from 2, 4, and 6 to protect concealment.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
