Background

Sexual offenses encompass a diverse array of behaviors across various contexts, affecting numerous individuals. Despite the prevalence of sexual offending among adolescents, there is still a limited understanding of this population. To contribute further to the literature in this field, the present study was conducted to compare a group of male adolescents convicted of sexual offenses with a control group in terms of reflective functioning (RF), emotion regulation (ER) strategies, and emotion dysregulation (ED).

Methods

60 male adolescents aged 12 to 18 years (M = 16.90; SD = 0.97) who had been convicted of at least one serious sexual offense were recruited from male adolescents referred by juvenile courts to the Legal Medicine Organization in Mashhad, Iran, and compared with a control group of non-offending adolescents consisting of 60 male adolescents aged 12 to 18 years (M = 16.97; SD = 0.82) who were attending school. The groups were matched on age and education level.

Results

A comparison between these two groups revealed that adolescents with a history of sexual offending exhibited poorer RF capacity, greater use of suppression as an ER strategy, and higher scores in all ED domains (p’s < 0.001) except non-acceptance of emotional responses compared with the control group.

Conclusions

Results suggest that RF, ER strategies, and ED need to be considered as important psychological factors in understanding and treating adolescents with a history of sexual offending.

Sexual offenses entail a broad range of behaviors in various situations that victimize a multitude of individuals [1]. In 2014, adolescents accounted for 21% of all arrests for sexual offenses in the United States [2]. Rates of sexual offenses committed by juveniles also vary from 5 to 24% in Europe [3]. Despite being a significant public health issue, research on sexual offending has focused predominantly on adult offenders. Consequently, there is a limited understanding of adolescent sexual offending, leaving a critical gap in the literature that needs to be addressed [4]. Paying attention to these youth is essential, as studies have found that adolescents who engage in sexually abusive behavior constitute a distinct group from adults who sexually offend, differing in their risk factors [5], and having a lower risk of reoffending sexually [6]. According to a previous research, these adolescents appear to be more prone to non-sexual recidivism [7].

Given the multidimensional nature of sexual offending, a wide range of risk factors, including developmental, biological, societal, familial, and psychological factors have been explored to enhance our understanding of sexual offending and aid in developing more effective assessment and treatment programs for individuals who commit sexual offenses [1, 6]. In terms of psychological factors, the literature suggests that deficits in reflective functioning (RF; [8]) and emotion regulation (ER; [9]) could contribute to sexual offending. However, most studies highlighting the role of these variables in sexual offending are derived from samples of adult offenders, and their generalizability to adolescents who have sexually offended remains uncertain. Therefore, there is a need for studies that examine these psychological variables specifically in the context of adolescents involved in sexual offending. In the following sections, we will delve into the existing literature that explores the complex relationships between these variables and sexual offending. Through this analysis, we aim to underscore a critical gap in the current literature concerning these variables, particularly in relation to young people who have been involved in sexual offending.

Reflective functioning and sexual offending

Mentalization is a particular dimension of social cognition that explains how people make sense of their social world by envisioning their mental states and those of others (e.g., feelings, beliefs, intentions, and desires) to make sense of their social world [10]. The concept of mentalization is multidimensional and overlaps with several constructs, such as theory of mind (ToM), mindfulness, perspective-taking, and empathy [11]. The term RF describes the psychological processes that underlie the ability to mentalize and provides a framework for assessing mentalization [12].

It has been found that lower levels of RF prevail to varying degrees in both adult [13] and young [14] samples of offenders which is manifested through a detachment from the needs and feelings of others or an inability to take into account how one’s actions affect other people [15]. Levinson and Fonagy [13] demonstrated that the RF of adult prisoners with violent offenses was significantly lower than that of those who had committed non-violent offenses or individuals with personality disorders. Another study also reported that compared with non-offending adolescents, juvenile offenders had lower RF scores [16]. These findings support the hypothesis that the inability to reflect on one’s mental state and that of others may play an important role in criminal behavior.

Research has also indicated a possible link between RF impairments and sexual offending. According to Fonagy [17], a lack of RF capacity may lead to the development of violent behavior, including sexual violence, by reducing empathy and a sense of responsibility for actions, enabling the treatment of others as physical objects and facilitating the development of cognitive distortions related to unacceptable conduct. In addition, there is ample indirect evidence about associations of deficits in other mentalizing-related capacities, such as ToM, empathy, and perspective-taking with sexual offending [18, 19]. For instance, Ward et al. [20] suggested that deficits in ToM are likely to lead to psychological problems including intimacy deficits, difficulties with empathy, and cognitive distortions, all of which have been identified as core features of individuals who commit sexual offenses.

Despite the established conceptual links between RF impairment and sexual offending, to the best of our knowledge, only one study has examined RF in juveniles with a history of sexual offending. Using a multiple-case design, this study found significant difficulties in perspective-taking, RF, and empathy in eight adolescents who engaged in harmful sexual behavior [21]. Although findings from this study suggest that RF may be a relevant construct in the context of sexual offending in adolescents, the small sample size, the lack of inclusion of a control group of non-offending adolescents, and the non-use of appropriate and valid measures of RF are among the limitations of this study that should be addressed in future studies.

Emotion regulation and sexual offending

Research has consistently shown that sexual offenders typically have problems with self-regulation [22], especially ER [9, 23]. Many individuals who sexually offend may struggle to differentiate, recognize, and express their emotions, often resorting to maladaptive strategies to suppress negative emotions [24]. Such ER difficulties can impair their ability to control their impulses when faced with sexual arousal, increasing the likelihood of using coercive means for sexual gratification [25]. In line with this, treatments such as multiple-family group intervention have been developed to reduce maladaptive emotion regulation in male adolescents incarcerated for sexual offenses [26].

The concept of ER reflects processes by which individuals employ a variety of strategies to influence what emotions they have, when they experience them, and how those emotions are experienced and expressed [27]. The process model of ER distinguishes ER strategies according to the timing of their main influence on the emotion-generating process, with a focus on cognitive reappraisal and expressive suppression. Cognitive reappraisal is an antecedent-focused strategy in which a potentially emotionally charged situation is interpreted in a non-emotional way. In contrast, expressive suppression is a response-focused strategy in which ongoing emotional-expressive behavior is inhibited. When analyzing these two forms of ER strategies, it is repeatedly shown that reappraisal is preferable to suppression as the latter is associated with reduced manifestation and experience of positive and negative emotions [28]. In addition, chronic and rigid use of expressive suppression appears to be a trigger for violence and aggressive behavior [29]. Regarding the relationship between the extent of use of these two ER strategies and sexual offending, Gillespie et al. [30] reported that adults who sexually offended showed no significant differences in the use of these specific strategies (i.e., cognitive reappraisal and expressive suppression) compared to the community sample. However, the sample of this study included adults with a history of sexual offending, which limits the generalizability of the results to adolescent population.

While certain conceptualizations of ER place a strong emphasis on the employment of ER strategies for reducing emotional arousal and controlling emotional experience and expression [31], others suggest that ER may be conceptualized as involving (a) awareness and understanding of emotions, (b) accepting emotional responses, (c) being able to control one’s impulses and participate in goal-directed behaviors when feeling negative emotions, and (d) the flexibility to employ situationally appropriate ER strategies to adjust emotional responses as needed to fulfill personal goals and situational demands. The relative presence of deficits in one or more of these domains would indicate difficulties in ER, or emotion dysregulation (ED;[32]). Research suggests that the risk of recidivism in certain types of crimes among juveniles is related to ED [33].

ED has also been recognized as highly problematic in adults who have committed sexual offenses [34]. However, to the best of our knowledge, only one study has examined ED in adolescents with a history of sexual offending [35], and its findings diverge from those observed in adults [30]. In this sole study, Jones et al. [35] reported that adolescents who had committed sexual offenses exhibited greater difficulties in all ER domains, except awareness and acceptance of emotions, compared to non-offending controls. Conversely, Gillespie et al. [30] found that sexually offending adults reported significantly more impairments in the acceptance of emotional responses compared to a community sample. Taken together, these findings highlight the need for more studies to comprehensively examine ED among adolescents who have committed sexual offenses compared to non-offending juveniles. Further research is also essential to clarify which specific ED domains are pertinent to adolescent sexual offending.

The present study

In the present study, we aimed to examine differences in RF, ER strategies, and ED in a group of male adolescents with a history of sexual offending and a comparison group of non-offending adolescents from the general population. In terms of RF, existing theoretical frameworks suggest that adults with sexual offenses tend to have lower levels of RF [8]. However, due to the limited literature on this topic on adolescents with a history of sexual offending, no definitive hypothesis was made regarding possible differences in RF between the two groups. Furthermore, previous studies with adult offenders found no significant differences between males with a history of sexual offending and control subjects in terms of the use of different ER strategies [30]. However, given the potential disparities between the adolescent and adult samples described above, no definitive hypotheses were made regarding possible differences in the use of cognitive reappraisal and/or expressive suppression as ER strategies between the groups. Concerning ED, consistent with previous research [35], it was hypothesized that adolescents with a history of sexual offending would exhibit elevated levels of ED compared to controls. Nevertheless, no solid hypotheses were formulated regarding possible differences in specific ED domains.

Method

Participants and procedure

This cross-sectional comparative study consisted of 120 male adolescents (aged 12 to 18 years) who were divided into two groups: Adolescents with a history of sexual offending and a control group of non-offending adolescents. The sexual offending sample was recruited from a population of adolescents who were referred for mental health evaluation to the Legal Medicine Organization in Mashhad by juvenile courts from July 2021 to June 2022. Based on their judicial record, 74 adolescents who had been convicted of at least one serious sexual offense, including rape and molestation of a victim of any age, were invited to participate in the study. Fourteen adolescents declined our invitation. Consequently, data was collected from 60 male adolescents (Mean age = 16.90; SD = 0.97) who had committed sexual offenses within one year prior to participation in the study. All participants were living with their families under court supervision at the time of data collection.

For the control group of non-offending adolescents, 60 male adolescents (Mean age = 16.97; SD = 0.82) who had no history of any criminal activity were recruited from public school registries in Mashhad city. The exclusion criteria for both of these groups were significant intellectual and developmental disabilities, inability to read above a fifth-grade reading level, and a clinical history of severe mental disorders such as schizophrenia and psychosis-related disorders and affective disorders, as assessed by court reports (offender sample) and psychiatric records (control sample). The two groups were matched in terms of age and education.

For data collection from the sexual offending sample, eligible participants were invited to attend an appointment with their legal guardians (one of their parents) where they completed consent forms and questionnaires. Before participation, they signed consent forms after receiving information about the study’s objectives and the voluntary and confidential nature of their involvement. The data collection process was supervised by a clinical psychologist serving as the lead investigator. Similar procedures were employed for collecting data from school-attending adolescents, except they completed the measures in their classrooms under the supervision of a specially trained research assistant. The study received formal approval from the ethics review board of the Iran University of Medical Sciences (IR.IUMS.REC.1400.214).

Measures1

Reflective functioning questionnaire for Youth (RFQ-Y)

The RFQ-Y [36] is a 46-item self-report questionnaire that measures RF in adolescents. In this questionnaire, adolescents are asked to rate statements about their understanding of their own and others’ mental states on a six-point Likert scale ranging from 1 (“strongly disagree”) to 6 (“strongly agree”). The answers are then summed up to compute a total score, with higher scores indicating a greater RF capacity. A preliminary study by Esmaeilinasab et al. (2024) has demonstrated promising psychometric properties of the Persian version of the RFQ-Y in adolescents.

Emotion regulation questionnaire for children and adolescents (ERQ–CA)

The ERQ-CA [37] is a revised version of the self-report Emotion Regulation Questionnaire (ERQ;[31])which evaluates the ER strategies of cognitive reappraisal and expressive suppression in children and adolescents. It comprises 10 items rated on a five-point Likert scale ranging from 1 (“strongly disagree”) to 5 (“strongly agree”). Regarding the validity and reliability of its subscales, the Persian version of the ERQ-CA has demonstrated strong psychometric qualities [38].

Difficulties in emotion regulation scale (DERS)

The DERS [32] is a 36-item measure that assesses difficulties in ER. The items of this instrument are rated on a five-point Likert scale ranging from 1 (“almost never”) to 5 (“almost always”), comprising six subscales: lack of emotional awareness (Awareness), poor emotional clarity (Clarity), non-acceptance of emotional responses (Non-acceptance), impulsive control difficulties (Impulse), difficulties engaging in goal-directed behaviors (Goals), and limited access to emotion regulation strategies (Strategies). Higher scores indicate greater difficulties in the ER. In the present study, we administered the Persian version of the DERS, which has shown good internal consistency and validity in previous research with Iranian adolescents [39].

Data analyses

In the present study, SPSS 20 software was used for data entry and statistical analyses. The normality of the distribution of the study variables was assessed using the Kolmogorov–Smirnov test which indicated that the data followed a normal distribution (p >.05). One-way analysis of variance (ANOVA) and multivariate analysis of variance (MANOVA) were then employed to compare the two groups on the study variables, while partial eta squared (ηp2) values of 0.01, 0.06, and 0.14 were interpreted as small, medium, and large effects, respectively. Given the numerous group comparison tests, the alpha was set at 0.001 to balance type I and type II errors.

Results

Table 1 shows that the groups did not differ significantly in demographic variables, including age and education level (p >.05). Descriptive statistics for all the study variables are presented in Table 2. One-way analysis of variance (ANOVA) was first employed to scrutinize group differences in the RFQ-Y total score. The results revealed significantly lower scores in the group with a history of sexual offending than in the control group [F (1, 118) = 31.87, p <.001, ηp2 = 0.21]. Regarding the ERQ-CA scores, the MANOVA test indicated a significant influence of the composite dependent variable, comprising the ERQ-CA Cognitive Reappraisal and Expressive Suppression subscales [Wilks’ Lambda = 0.85, F (1, 118) = 10.61, p <.001, ηp2 = 0.15]. However, univariate tests revealed a significant effect of group only on the ERQ-CA Expressive Suppression subscale [F (1, 118) = 15.80, p <.001, ηp2 = 0.12]. Furthermore, a MANOVA test was conducted to explore group differences in DERS scores. The multivariate tests showed a significant effect of the group variable on the composite dependent variable (i.e., the DERS subscales; Wilks’ Lambda = 0.71, F (1, 118) = 7.53, p <.001, ηp2 = 0.29.) As detailed in Table 2, univariate tests further revealed significant effects of the group variable on the DERS subscales of Goals [F (1, 118) = 22.63, p <.001, ηp2 = 0.16], Impulse [F (1, 118) = 28.89, p <.001, ηp2 = 0.20], Awareness [F (1, 118) = 11.67, p <.001, ηp2 = 0.09], Strategies [F (1, 118) = 12.33, p <.001, ηp2 = 0.09], and Clarity [F (1, 118) = 17.56, p <.001, ηp2 = 0.13].Table 1 The comparison of groups in age and education

Discussion

This study aimed to examine differences in RF, ER strategies, and ED between adolescents who committed sexual offenses and a control group of non-offenders. Overall, adolescents with a history of sexual offending showed lower levels of RF, higher use of expressive suppression as an ER strategy, and greater ED compared with those in the control group.

The significant difference between the RF scores of adolescents with sexual offenses and those of the non-offender sample suggests that these youth may have limited capacity to think about or “mentalize” their own mental states or the mental states of others in terms of feelings, thoughts, beliefs, or motivation. These findings are comparable to those from a sample of adolescent offenders with harmful sexual behavior who showed significant problems with RF [21]. Greater deficits in RF have also been observed in male juvenile offenders compared to non-offending adolescents [16]. Keenan and Ward [40] argued that difficulties in understanding and attributing different types of mental states to other people are likely to lead to a lack of empathy and could create an interpersonal context in which inappropriate and potentially abusive behaviors such as sexual assault could occur. Taken together, these findings are in line with Allen et al.’s [41] assumption that “mind-blindness”, defined as the inhibition of mentalizing, allows one to distance oneself from the victim, thus facilitating the acting out of one’s aggressive impulses.

In terms of ER strategies, the findings of this study showed that adolescents who had sexually offended scored higher on expressive suppression than the non-offender sample. These results appear to contrast with those of Gillespie et al. [30], who found no significant differences between different groups of adults who had committed sexual, violent, or homicide offenses, and a community sample in terms of cognitive reappraisal and expressive suppression. One plausible explanation for this controversial pattern of findings is that conclusions derived from studies of adults who have sexually offended may not be generalizable to explain sexually abusive behavior in adolescents [42]. Our findings are in line with those of Habib et al. [15], who reported that incarcerated males were more likely to use expressive suppression than normative samples from other studies in Lebanon and the Arab region. There is also evidence that the inflexible use of expressive suppression may contribute to aggressive behavior by increasing negative affect, reducing the individual’s inhibition against aggression, impairing decision-making processes through the depletion of cognitive resources, decreasing social networks, increasing physiological arousal, and making it more difficult to cope with challenging situations [43]. When considering the other ER strategy, we found no significant differences between the two groups in terms of cognitive reappraisal, suggesting that adolescents who had committed sexual offenses did not have problems in reappraising their emotions compared to the non-offender control group. This non-significant result is consistent with the conclusions of a previous study, which found no differences between juveniles who had committed sexual offenses and the control group in terms of reappraisal abilities [35]. However, given the dearth of research on specific ER strategies in sexually offending adolescents, further studies are needed to replicate these findings.

Our results regarding ED showed significant differences between the two groups in all domains of ED except non-acceptance of emotional responses. In other words, adolescents who had sexually offended reported greater difficulties in being aware of and understanding their emotions, engaging in goal-directed behaviors and controlling impulsive behaviors when experiencing negative emotions, and using situationally appropriate ER strategies flexibly compared to those in the non-offending sample. Previous work suggests that men who sexually offend are often characterized by deficits in ER [44]. However, there is a paucity of research that has comprehensively assessed ED in adolescents charged with sexual crimes. Our findings support previous research [35], demonstrating that ED may represent a characteristic feature of adolescents who commit sexual offenses. This assertion is supported by Moriarty et al. [45] who also found that adolescents who become sexually delinquent exhibit deficits in emotional understanding and are less able to repair unpleasant moods and prolong positive moods. The findings from this study seem to be inconsistent with those of a previous study that found evidence of impairments in the acceptance of emotional responses in adult males who had committed sexual offenses [30]. It is possible that the use of an adult sample in the latter study may explain these contradictory findings. Nonetheless, our findings suggest that ED may serve as a significant variable in the context of sexual offending among adolescents.

The findings from the current study should be interpreted within the context of several limitations. First, the use of self-report measures for data collection may lead to shared method variance, potentially influencing our results. Thus, future studies should employ multi-informant approaches in data gathering to enhance the robustness of findings. Second, the Expressive Suppression subscale of the ERQ-CA and the Non-acceptance and Awareness subscales of the DERS did not demonstrate acceptable alpha coefficients. This may be attributed to the limited number of items in these subscales, as Cronbach’s alpha is sensitive to item count. However, the MIC provides a more reliable indicator in these cases, as it is less affected by the length of the scales. Future research should examine whether these findings are unique to this study or if they generalize to other populations and settings. Third, our study utilized a cross-sectional design which precludes causal inferences. Longitudinal studies are needed to elucidate the causal relationships between the variables examined in this study and adolescent sexual offending. Further, the sample size in our study was relatively small. Future research efforts could strengthen the generalizability and reliability of our findings by including larger sample sizes. Finally, another limitation of this study is the lack of consideration of additional variables that could moderate the observed differences. Future studies should incorporate variables such as the age of the victims, reoffender versus non-reoffender status, relationships to the victims (known versus unknown), and offender typologies (sex-only or specialists versus sex-plus or generalist offenders). Including these variables would provide a more nuanced understanding of the factors distinguishing different types of adolescents who sexually offend.

Conclusion

This study builds upon previous research by providing new insights into the reflective functioning capacity and emotion regulation abilities of adolescents who have committed sexual offenses. In short, our findings indicate that adolescents with a history of sexual offending appear to be characterized by lower levels of RF, higher use of suppression as an ER strategy, and greater difficulties in ER compared to non-offending controls. This knowledge adds important information to the growing body of research on adolescent sexual offending. These findings also suggest that adolescents who commit sexual offenses may benefit from mentalization and emotion regulation-based interventions aimed at improving RF and enhancing ER skills. Therefore, findings from this study may encourage future studies to examine whether incorporating such therapeutic approaches into intervention programs can effectively reduce the risk of sexual recidivism in adolescents.
