The Effectiveness of an Individualized Intervention for Perpetrators of Child Sexual Abuse

Basic Empathy Scale - Adapted (BES Adapted; Salas-Wright et al., 2012; Portuguese version: Pechorro et al., 2015).

时间窗: immediately post-intervention and 3-month follow-up

The study protocol will include the Basic Empathy Scale - Adapted (BES Adapted; Salas-Wright et al., 2012; Portuguese version: Pechorro et al., 2015). The BES Adapted is a self-report measure with two dimensions: affective empathy which encompasses three items, and cognitive empathy which includes four items. Each item is scored on a 5-point ordinal scale (1 = strongly disagree to 5 = strongly agree). The scale does not have a cutoff point, but higher scores indicate greater empathy. In the "affective empathy" factor, scores can vary between 3 and 15, in the "cognitive empathy" factor between 4 and 20. The total score can vary between 7 and 35.

Hanson Sex Attitude Questionnaire (HSAQ; Hanson et al., 1994; Portuguese version by Sousa et al., in press)

时间窗: immediately post-intervention and 3-month follow-up

The study protocol will include the Hanson Sex Attitude Questionnaire (HSAQ; Hanson et al., 1994; Portuguese version by Sousa et al., in press). The Portuguese version of HSAQ is a 38-items self-report measure designed to measure cognitive distortions about child sexual abuse and sexuality. Through a confirmatory factor analysis, it was possible to identify three independent factors, namely: Child as human beings (17 items), Sexual Drive (12 items), and Sexual entitlement (9 items). Each item is scored on a 5-point ordinal scale (1 = strongly disagree to 5 = strongly agree). The scale does not have a cutoff point, but higher scores indicated more cognitive distortions. In factor 1, scores can vary between 17 and 85, in factor 2 from 12 to 60 and in factor 3 from 9 to 45.

Victim Empathy Distortion Scale (VES; Beckett & Fisher, 1994; Portuguese version: Sousa et al., in press)

时间窗: immediately post-intervention and 3-month follow-up

The study protocol will include the Victim Empathy Distortion Scale (VES; Beckett \& Fisher, 1994; Portuguese version: Sousa et al., in press. VES is a 28-item questionnaire to assess the individual's understanding of the impact of offending on their victims. The Portuguese version of the scale has two factors: positive misattributions of pleasure in sexual abuse (18 items), and negative attributions of child sexual abuse (10 items). The scale does not have a cutoff point but higher scores on factor one indicated more cognitive distortions about child sexual abuse, while a higher score in factor 2 represents a greater awareness of the impact that the abusive situation has on their victim. The items are rated on a 5-point scale ranging from 0 (strongly disagree) to 4 (strongly agree). In factor 1, scores can vary between 18 and 90, in factor 2 between 10 and 50.

Young Schema Questionnaire - YSQ-S3 (Young, 2005; Portuguese version by Pinto-Gouveia, Rijo, & Salvador, unpublished).

时间窗: immediately post-intervention and 3-month follow-up

The study protocol will include the Young Schema Questionnaire - YSQ-S3 (Young, 2005; Portuguese version by Pinto-Gouveia, Rijo, \& Salvador, unpublished). The YSQ-S3 is a self-report questionnaire comprising 90 items. It measures 18 different EMS proposed by Young (1990) using a 6-point type scale (1 = completely untrue to me; 6 = to describe me perfectly). We generally consider any score of 3 or more on a schema to be meaningful. The total score can vary between 0 and 6.

Inventory of Interpersonal Problems (IIP-32; Barkham et al., 1996; Portuguese version by Faustino & Vasco, 2020).

时间窗: immediately post-intervention and 3-month follow-up

IIP-32 is a self-report instrument that focuses on the assessment of eight interpersonal domains: domineering/controlling; intrusive-needy; self-sacrificing; overly accommodating; nonassertive; socially avoidant ; cold-distant; and vindictive/self-centered. It is composed by 32 items rated along a 5-point Likert type scale response. No normative data are available.

Sexual Violence Risk (SVR-20; Boer et al., 1997; Portuguese version: Gonçalves & Vieira, 2004).

时间窗: immediately post-intervention and 3-month follow-up

SVR-20 is a structured professional judgment assessment instrument intended for use with perpetrators of sexual crimes. The instrument contains 20 items that are considered risk factors for recidivism in sexual crimes. Professionals use clinical judgment and file information to rate each of the 20 items as either "not present", "possibly or partially present" or "present". The instrument contains three sections: psychosocial adjustment (7 items), sex offenses (7 items) and future plans (2 items). the scale does not have a cutoff point.

Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1979, 1989; Portuguese version: Pechorro et al., 2011).

时间窗: immediately post-intervention and 3-month follow-up

The study protocol will included the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1979, 1989; Portuguese version: Pechorro et al., 2011). RSES is a brief self-report scale that assesses self-esteem. Responses are coded on a 4-point scale ranging from 0 (strongly disagree) to 3 (strongly agree). the scale does not have a cutoff point, but higher results reveal higher levels of self-esteem. The total score can vary between 0 and 30.

Brief Symptoms Inventory (BSI; Derogatis, 2001; Portuguese version: Canavarro, 2007).

时间窗: immediately post-intervention and 3-month follow-up

The study protocol will include the Brief Symptoms Inventory (BSI; Derogatis, 2001; Portuguese version: Canavarro, 2007). BSI is a 53-item self-report instrument that measures psychopathological symptoms during the previous 7 days, on a five-point scale (0 = not at all to 4 = extremely). The inventory was composed of nine dimensions: somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. The cut-off point for the somatization scale is 0.6, for the obsessions-compulsions scale is 1.6, for the interpersonal sensitivity scale is 1.1, for the depression scale is 1.2, for the anxiety scale is 1.3, for the hostility scale is 1.1, for the phobic anxiety scale is 0.6, for the paranoid ideation scale is 1.3, and for the psychoticism scale is 0.9 (Canavarro, 2007). The total score can vary between 0 and 4.
