The Compulsive Sexual Behavior Disorder Diagnostic Inventory (CSBD-DI)<\/strong> is an internationally validated screening instrument and diagnostic assessment measure developed by Joshua B. Grubbs<\/a> and an international consortium of psychometricians and clinical scientists (Grubbs et al., 2023<\/a>). Designed to operationalize the clinical criteria established for Compulsive Sexual Behavior Disorder (CSBD; code 6C72) in the World Health Organization’s International Classification of Diseases, Eleventh Revision (ICD-11)<\/a>, the inventory also bridges the historical diagnostic criteria formulated for Hypersexual Disorder (HD) proposed for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)<\/a>. The inventory consists of a 9-item research pool and a refined 7-item core diagnostic screener that explicitly probes the 6-month temporal requirement outlined in the ICD-11 diagnostic guidelines.<\/p>\n Psychometrically evaluated across large-scale, cross-national community and nationally representative samples from the United States, Poland, Hungary, Germany, and Malaysia (totaling over 10,000 respondents), the 7-item core CSBD-DI demonstrates a unidimensional latent factor structure with exceptional model fit across diverse sociocultural and linguistic contexts. Confirmatory factor analysis (CFA) supports residual (strict) measurement invariance across national samples (United States, Poland, and Hungary) and scalar (strong) invariance across gender identities. Internal consistency estimates across non-clinical, community, and nationally representative samples demonstrate robust reliability, with Cronbach’s alpha ($\u0007lpha$<\/span>) and McDonald’s omega ($\\omega$<\/span>) coefficients routinely ranging between 0.78 and 0.82 in representative cohorts, alongside standardized factor loadings exceeding 0.47 for core items. Receiver Operating Characteristic (ROC) curve analyses indicate that an endorsement threshold of $ge 1$<\/span> or $ge 2$<\/span> active symptoms over the past 6 months provides optimal balance between clinical sensitivity and specificity for preliminary triage and epidemiological screening. The CSBD-DI provides clinicians and behavioral researchers with an empirical, non-pathologizing instrument that discriminates between normative high sexual desire, moral incongruence, and true compulsive sexual dysregulation.<\/p>\n Compulsive Sexual Behavior Disorder, CSBD-DI, ICD-11, Hypersexual Disorder, Behavioral Addiction, Psychometrics, Measurement Invariance, Sexual Health, Screening Tool, Diagnostic Assessment, Impulse Control Disorders<\/p>\n The Compulsive Sexual Behavior Disorder Diagnostic Inventory was created through an international collaboration of clinical psychologists, psychiatrists, and behavioral addiction researchers:<\/p>\n The primary purpose of the Compulsive Sexual Behavior Disorder Diagnostic Inventory (CSBD-DI) is to serve as an empirically validated, brief screening assessment and clinical diagnostic evaluation tool calibrated specifically against contemporary international nosological standards. For several decades, the clinical study and psychometric measurement of dysregulated sexual behavior were hindered by contentious diagnostic nomenclature, conceptual ambiguities, and unstandardized psychometric instruments. Historical terms such as “sexual addiction,” “nymphomania,” “satyriasis,” “hypersexuality,” and “sexual compulsivity” often conflated frequent sexual behavior, unconventional sexual preferences, non-pathological high libido, and subjective distress stemming from moral, religious, or sociocultural disapproval with genuine psychiatric impairment (Kraus et al., 2018<\/a>).<\/p>\n With the formal codification of Compulsive Sexual Behavior Disorder (CSBD; code 6C72) under the category of Impulse Control Disorders in the World Health Organization’s ICD-11, the field required an updated psychometric tool that strictly reflects the diagnostic criteria established by international consensus. The ICD-11 defines CSBD as a persistent pattern of failure to control intense, repetitive sexual impulses or urges resulting in repetitive sexual behavior over an extended period (typically 6 months or longer), characterized by: (a) repetitive sexual activities becoming a central focus of the person’s life to the point of neglecting health, personal care, or other interests, activities, and responsibilities; (b) numerous unsuccessful efforts to significantly reduce repetitive sexual behavior; (c) continued engagement in repetitive sexual behavior despite adverse consequences or deriving little to no satisfaction from it; and (d) marked distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning.<\/p>\n The CSBD-DI was engineered to achieve three primary clinical and academic objectives:<\/p>\n The CSBD-DI assesses the multidimensional construct of compulsive sexual behavior disorder, conceptualized within the framework of impulse control dysregulation and behavioral addictions. The instrument captures key operational dimensions:<\/p>\n At the center of CSBD is the impaired capacity to inhibit, regulate, or stop repetitive sexual behaviors. Clinically, this manifests as an inability to control intrusive sexual urges and fantasies, leading to behavioral enactments that violate personal boundaries or pre-established self-commitments. In the CSBD-DI, this construct is represented by items assessing subjective loss of control over sexual urges and repeated failures in sustained efforts to reduce, limit, or stop sexual behavior. Individuals experiencing this dimension often engage in cyclical attempts at abstinence or moderation, followed by rapid relapse and escalations in compulsive enactments.<\/p>\n This dimension operationalizes the disproportionate allocation of psychological, cognitive, and temporal resources toward sexual pursuits. Compulsive sexual activity becomes the organizing axis of the individual’s daily life, crowding out normative developmental, occupational, relational, and physical health activities. The construct captures the extensive time consumed not only in executing sexual acts (such as continuous hours spent viewing pornography, cybersex, engaging in anonymous sexual encounters, or frequenting adult entertainment venues) but also in the cognitive planning, searching, arranging, and subsequent physical or emotional recovery required. As a consequence, physical health, personal hygiene, sleep architecture, familial commitments, and vocational obligations are progressively neglected.<\/p>\n A hallmark indicator of behavioral compulsivity is continued enactment of the behavior in the face of cumulative, severe, and tangible negative outcomes. This construct reflects behavioral persistence despite demonstrable relationship dissolution, professional reprimands or job loss, substantial financial debt, medical complications (such as recurrent sexually transmitted infections or genital physical trauma), or legal entanglements. In individuals without CSBD, encountering adverse consequences typically induces behavioral cessation or modification; in individuals with CSBD, the behavioral pattern persists undeterred, demonstrating profound reward hypersensitivity, risk neglect, and executive inhibitory dysfunction.<\/p>\n A critical symptom unique to the ICD-11 diagnostic conceptualization of CSBD is the phenomenon wherein repetitive sexual behaviors persist even when the individual derives little, negligible, or no sexual pleasure or psychological satisfaction from the act. This reflects an operational divergence between “wanting” (incentive salience, craving) and “liking” (hedonic consumption), a neurobiological pattern characteristic of advanced addictive and compulsive processes. Sexual behavior shifts from appetitive, pleasure-seeking activity toward automated, stereotypic, ego-dystonic execution driven by compulsion or internal tension relief rather than authentic hedonic gratification.<\/p>\n The construct requires marked, clinically significant distress or functional disability in key life domains, including intimate relationships, family systems, peer networks, educational advancement, and occupational performance. Importantly, following ICD-11 guidance, this distress must stem directly from the behavioral dyscontrol and functional sequelae of the actions rather than exclusively from guilt, shame, or moral conflict regarding the moral acceptability of the sexual thoughts or acts.<\/p>\n The extended 9-item pool of the CSBD-DI incorporates two exploratory items evaluating the utilization of sexual behavior as an avoidant coping strategy or emotional regulation mechanism in response to dysphoric emotional states (such as anxiety, depression, boredom, or stress) and adverse life events. While these coping manifestations constituted core diagnostic criteria in Kafka’s (2010) proposed DSM-5 criteria for Hypersexual Disorder, the World Health Organization’s ICD-11 working group excluded them as necessary diagnostic criteria for CSBD, categorizing them instead as non-essential associated features. Consequently, while the full 9-item inventory retains these items for exploratory and comparative research, the psychometrically superior 7-item core CSBD-DI isolates the formal ICD-11 diagnostic criteria.<\/p>\n The conceptual architecture of the CSBD-DI is rooted in complementary neurobiological, cognitive-behavioral, and psychiatric theoretical models of behavioral addiction and impulse control disorders:<\/p>\n Adapted from the foundational work of Robinson and Berridge (1993)<\/a>, the incentive-sensitization theory posits that repeated engagement in highly rewarding, dopamine-stimulating behaviors produces progressive, persistent neuroadaptations in mesocorticolimbic dopamine circuits. Specifically, the neural systems mediating the subjective attribution of incentive salience (“wanting”) become hyper-sensitized to conditioned sexual cues, whereas the neural circuits underlying the hedonic reward experience (“liking”) remain unchanged or exhibit tolerance. This dissociation provides the theoretical foundation for the CSBD-DI item assessing persistent behavior despite “little or no sexual satisfaction”: the compulsive drive to engage in the behavior intensifies even as the emotional and physical pleasure derived from it diminishes.<\/p>\n Cognitive neuroscience frameworks of impulse control disorders conceptualize dysregulated behavior as an imbalance between two competing neurocognitive networks: an overactive, hyper-responsive bottom-up impulsive\/reward system (anchored in the ventral striatum and amygdala) and an under-functioning, compromised top-down reflective\/inhibitory control system (localized within the dorsolateral prefrontal cortex, anterior cingulate cortex, and inferior frontal gyrus) (Brand et al., 2016<\/a>; Brand et al., 2019<\/a>). In individuals with CSBD, acute exposure to sexual stimuli precipitates cue-reactivity, attentional bias, and intense craving, triggering an executive overload where top-down self-regulatory control collapses. This theoretical structure directly underpins the CSBD-DI items evaluating the subjective feeling of being unable to control urges and repeated failures to moderate or cease the behavior.<\/p>\n Developed by Brand et al. (2019)<\/a>, the I-PACE model offers a comprehensive theoretical framework for understanding the genesis, maintenance, and clinical exacerbation of specific internet-use disorders and behavioral addictions, including compulsive sexual behavior disorder and problematic pornography use. The model posits that predisposing core personal characteristics (e.g., personality traits, neurobiological vulnerabilities, psychopathology, early childhood adversity) interact with affective and cognitive variables (e.g., coping styles, implicit associations, craving, cognitive expectancies). As the disorder progresses, behavioral enactment shifts from initial goal-directed, pleasure-driven actions (positive reinforcement) to habitual, compulsive behaviors functioning to alleviate negative emotional states or internal distress (negative reinforcement). The inclusion of items assessing sexual behavior in response to stress and negative emotional states within the CSBD-DI research pool reflects this theoretical transition.<\/p>\n The CSBD-DI is situated squarely within an ongoing international psychiatric nosological debate. While the ICD-11 classified CSBD under Impulse Control Disorders due to perceived insufficient long-term longitudinal neurobiological evidence regarding withdrawal, tolerance, and neural progression (Grant et al., 2014<\/a>; Kraus et al., 2018<\/a>), many addiction medicine specialists and researchers advocate for its categorization as a behavioral addiction alongside Gambling Disorder and Gaming Disorder. The operationalization of CSBD-DI items captures behavioral phenomenology common to both classifications: impaired impulse regulation, behavioral salience, relapse, tolerance-like persistence without pleasure, and functional impairment.<\/p>\n The psychometric properties of the CSBD-DI were systematically examined across two comprehensive studies encompassing diverse international cohorts (Grubbs et al., 2023<\/a>). Study 1 utilized large community samples from Malaysia, the United States, Hungary, and Germany. Study 2 expanded this validation using high-powered, nationally representative adult panels from the United States ($N = 1,029$<\/span>), Poland ($N = 1,023$<\/span>), and Hungary ($N = 1,003$<\/span>).<\/p>\n Across all cultural and linguistic cohorts, the 7-item CSBD-DI demonstrated strong convergent validity with established, legacy measures of out-of-control sexual behavior, problematic pornography use, and sexual compulsivity. Specifically, CSBD-DI scores exhibited substantial, statistically significant positive correlations with:<\/p>\n Crucially, the CSBD-DI demonstrated divergent validity from measures of moral incongruence and general non-pathological sexual desire. While scores on legacy screening tools frequently inflated clinical classifications among highly religious or morally conservative individuals who merely viewed pornography infrequently, the CSBD-DI’s strict focus on objective behavioral consequences and functional impairment substantially attenuated correlations with moral disapproval scales. Furthermore, the scale demonstrated weak-to-moderate correlations with general sexual desire, confirming that the CSBD-DI does not pathologize high levels of healthy, well-integrated libido.<\/p>\n To determine clinical screening thresholds, Receiver Operating Characteristic (ROC) curve analyses were conducted against established external criteria, including clinical thresholds on the Hypersexual Behavior Inventory (HBI cutoff $ge 53$<\/span>) and clinician-adjudicated diagnostic evaluations:<\/p>\n The reliability of the CSBD-DI has been rigorously documented across multiple languages, cultural environments, and sampling methodologies.<\/p>\n Across both the developmental community samples and the nationally representative cohorts in Study 2 (Grubbs et al., 2023<\/a>), the 7-item core CSBD-DI demonstrated sound internal consistency:<\/p>\n Psychometric analyses consistently demonstrated that the 7-item core version (excluding the two mood-regulation coping items, Items 8 and 9) exhibited higher internal consistency, cleaner factor structures, and superior average variance extracted (AVE) compared to the original 9-item candidate pool. Items 8 and 9 demonstrated idiosyncratic endorsement distributions in general community populations, where individuals frequently endorse using sexual behavior to alleviate stress or boredom without experiencing any compulsive dysregulation, loss of control, or impairment. Dropping these two items improved scale reliability and eliminated unwanted construct variance.<\/p>\n The structural validity of the CSBD-DI was evaluated using both Exploratory Factor Analysis (EFA) during preliminary item calibration and extensive Confirmatory Factor Analysis (CFA) across diverse international independent cohorts.<\/p>\n Confirmatory factor models tested the theoretical unidimensionality of the core 7-item scale, wherein all items load onto a single general latent CSBD factor. The 7-item unifactorial model demonstrated superior goodness-of-fit indices across all national cohorts compared to the 9-item structure:<\/p>\n To verify that the CSBD-DI measures the identical psychological construct with equivalent operational scaling across disparate populations, multigroup confirmatory factor analysis (MGCFA) was conducted testing four sequential, increasingly restrictive levels of invariance: configural, metric (weak), scalar (strong), and residual (strict) invariance (Grubbs et al., 2023<\/a>):<\/p>\n Below are primary foundational references for the development, theoretical framing, and psychometric validation of the CSBD-DI:<\/p>\n2.
