84 Chapter 3 Self-sufficiency Self-sufficiency will be measured with the Dutch version of the Self-Sufficiency Matrix (SSM-D) at baseline, and 3, 6, 9, 12 and 18 months after baseline assessment. The SSM-D is a 13-item 5-point Likert-type assessment tool of treatment outcomes (Culhane, Gross, Parker, Poppe, & Sykes, 2008; Fassaert et al., 2014; Lauriks et al., 2017; Lauriks et al., 2013). Self-sufficiency on 11 important domains of life, such as physical health, mental health, addiction, income, housing, social network, social participation, and justice, are measured. The SSM-D is validated for the Dutch population (Fassaert et al., 2014) and demonstrated adequate psychometric properties (Bannink, Broeren, Heydelberg, van ’t Klooster, & Raat, 2015; Fassaert, Lauriks, van de Weerd, de Wit, & Buster, 2013). Potential mediators and moderators Diagnostic classifications The presence of current psychiatric disorders based on the Diagnostic and Statistical Manual of Mental Disorders (Fourth edition, Text Revision and Fifth edition; DSM-IV-TR/5) and the International Classification of Diseases (Tenth revision; ICD-10) will be assessed with the Dutch version of the MINI International Neuropsychiatric Interview-plus (MINI-plus; version 5.0) (Lecrubier et al., 1997; Sheehan et al., 1998). The MINI-plus is a structured, clinician-administered, diagnostic instrument that consists of several sections (A-Z) that address different DSM-IV-TR and ICD-10 classifications. The Dutch version of the MINI-plus is found to be a reliable and validated structured diagnostic instrument (Lecrubier et al., 1997). Section A-J, M, Q and W of the MINI-plus will be administered by the researchers at baseline to assess the presence of depressive disorders, suicidality, bipolar disorders, anxiety disorders, posttraumatic stress disorder, psychotic disorders, antisocial personality disorder and attention deficit hyperactivity disorder, respectively. In addition, DSM-IV-TR/5 classifications will be collected from electronic patient files at baseline. Trauma Maltreatment histories will be measured with the Dutch version of the Childhood Trauma Questionnaire-Short Form (CTQ-SF), a 27-item5-point Likert-type self-report questionnaire (Bernstein et al., 2003; Thombs, Bernstein, Lobbestael, & Arntz, 2009). The CTQ-SF consists of five subscales: physical abuse, sexual abuse, emotional abuse, physical neglect, and emotional neglect. The questionnaire is validated for a Dutch population (Thombs et al., 2009) and has demonstrated high to acceptable internal consistency, good convergent and discriminant validity, and good criterion-related validity (Bernstein, Ahluvalia, Pogge, &
