The original Sexual Motivation Scale was developed by Gravel and colleagues in 2016 and is grounded in self-determination theory, one of the most influential frameworks in contemporary motivational psychology. Rather than treating sexual motivation as a single dial that runs from low to high, the scale maps it onto a multidimensional continuum. At one end lies amotivation, the absence of any drive toward sexual activity. Moving along the continuum, motivation can be external, driven by outside pressures or rewards; introjected, fueled by internal guilt or self-imposed expectations; identified, reflecting personally valued goals; integrated, where sexual behavior harmonizes with one’s core sense of self; and finally intrinsic, where the activity is pursued for its own inherent pleasure and satisfaction. This architecture allows researchers to ask not simply how motivated someone is, but why.

Translating a psychologically sensitive instrument is far more mechanical than running text through a dictionary, and the Iranian team followed a rigorous standardized forward-backward protocol. Bilingual translators independently rendered the original 24 items into Persian, and a separate set of translators, blind to the original wording, translated the Persian version back into English. Discrepancies between the back-translation and the source items were examined and reconciled, a process designed to catch subtle shifts in meaning that could distort what respondents actually answer. For a scale touching on sexuality in a culturally conservative context, preserving nuance is not a technical nicety but an absolute requirement for valid measurement.

Before any participant filled in a questionnaire, the translated items faced a panel of experts who judged their relevance and clarity using two established metrics: the content validity ratio, or CVR, and the content validity index, or CVI. Both indices quantify how strongly a panel agrees that each item is essential and representative of the construct it is meant to capture. The Persian SexMS performed well on both counts, achieving a CVI of 0.87 and a CVR of 0.89, figures that indicate satisfactory agreement among the expert reviewers and cleared the instrument for field testing.

The field test itself involved 394 married adults aged 18 to 60, recruited from health centers in Mashhad, a major city in northeastern Iran. Participants completed a demographic questionnaire alongside the Persian SexMS. Given the sensitive nature of the subject matter, the researchers implemented unusually careful privacy protocols. Respondents filled out the questionnaires alone in dedicated consultation rooms separated from routine clinical areas, ensuring both visual and auditory privacy. No names or contact details were collected; each form carried only a numerical identification code. Completed questionnaires went directly from participants into sealed, opaque collection boxes that healthcare center staff could not access, and participants were told explicitly that joining or withdrawing would have no effect on the care they received. These safeguards were designed to suppress social desirability bias, the well-documented tendency of people to answer sensitive questions in ways that make them look good.

The statistical centerpiece of the study was confirmatory factor analysis, or CFA, a technique that tests whether the pattern of responses actually matches the theoretical structure the scale claims to have, in this case six correlated factors corresponding to the six motivational types. The initial analysis flagged a problem: item 4, belonging to the intrinsic motivation subscale, showed a factor loading below the conventional 0.30 threshold, meaning it correlated too weakly with its intended factor to carry its weight. The researchers removed it and re-ran the analysis on the remaining 23 items. The re-specified model fit the data acceptably, with a chi-square to degrees-of-freedom ratio of 2.83, a comparative fit index of 0.90, an incremental fit index of 0.90, and a root mean square error of approximation of 0.068 with a 90 percent confidence interval of 0.061 to 0.076. In plain terms, the six-factor architecture of the original scale survived translation largely intact.

Reliability, the question of whether the instrument produces consistent measurements, was assessed in two complementary ways. Internal consistency examines whether items within each subscale correlate with one another as they should, and the Persian SexMS delivered a Cronbach’s alpha of 0.868 and a McDonald’s omega of 0.882, both comfortably within the range considered good for a multidimensional psychological scale. Test-retest stability was evaluated by asking participants to complete the scale a second time two weeks later, and the intraclass correlation coefficient came in at 0.87, a strong figure indicating that scores were highly stable over an interval long enough to filter out momentary mood swings but short enough that genuine motivation was unlikely to have shifted.

Beyond the headline statistics, the subscale scores offer an intriguing glimpse into the motivational profile of the sample. Integrated regulation, the form of motivation in which sexual behavior is experienced as fully congruent with one’s values and identity, yielded the highest mean score at 21.49 with a standard deviation of 5.44. Amotivation, the near-absence of any drive, scored lowest at 7.14 with a standard deviation of 4.74. The pattern is consistent with self-determination theory’s prediction that among well-functioning married adults, autonomous and self-endorsed forms of motivation tend to dominate over pressured or absent ones, though the authors present these as descriptive findings for the sample rather than population-level claims.

The practical implications extend well beyond academic curiosity. Sexual motivation is closely tied to sexual health, relationship satisfaction, and the assessment of conditions ranging from hypoactive desire to the psychological side effects of medical treatments. Until now, Persian-speaking clinicians and researchers lacked a validated multidimensional measure of this construct, forcing them to rely on unvalidated translations or single-item questions that collapse a rich motivational landscape into a crude summary. A psychometrically sound 23-item Persian SexMS opens the door to studies tracking how motivation profiles differ across age groups, marital durations, and clinical populations, and gives counselors a structured way to explore why a client’s desire has changed rather than merely how much.

The study, funded by Mashhad University of Medical Sciences as part of a master’s thesis, also stands as a case study in how careful measurement science works. Every step, from forward-backward translation to expert panel review, privacy-protected data collection, confirmatory factor analysis, and dual reliability testing, reflects the methodological discipline required before a questionnaire can be trusted. The authors caution that their validation applies to married Iranian adults recruited from health centers in one city, and further work in other regions and populations would strengthen generalizability. Still, the core message is clear: a decade after the original SexMS appeared, its theoretical backbone has now been shown to travel across languages and cultures, giving researchers in Iran and potentially the wider Persian-speaking world a rigorous instrument for investigating the motivations that animate one of the most intimate corners of human life.

Latent class analysis works by treating the patterns of answers across multiple survey indicators as signals of underlying, unobserved categories. In this study, the researchers measured five motivational indicators: arousal enhancement, relaxation, sexual satisfaction in a partner’s absence, boredom relief, and technology integration. Respondents rated how strongly each motive described their use of connected devices, and the analysis algorithm then searched for the number of classes, or profiles, that best explained the observed response patterns. A four-class solution emerged as the statistically optimal fit, meaning that the diversity of motivations among male teledildonics users could be efficiently summarized by four archetypes, each with its own internal logic, usage habits, and demographic signature.

The largest group, accounting for 38.2 percent of the sample, was labeled Solo Comfort Seekers. These users strongly endorsed the motive of sexual satisfaction in a partner’s absence, positioning the technology as a form of partner substitution rather than a novelty gadget. Their behavior was characterized by regular pairing of teledildonics with pornography, suggesting that the connected toy functions as one component within a broader solitary sexual routine mediated by digital content. For this group, the interactive and responsive qualities of the devices may simulate, at least in part, the presence of another person, filling a relational gap whether due to singleness, separation, or the ordinary rhythms of a relationship in which a partner is frequently away.

The second largest profile, the Low-Regulation Users at 30.3 percent, displayed the weakest endorsement of relaxation and boredom relief as motives. In other words, these men were not primarily using connected sex toys as tools for soothing stress or filling idle hours. Their engagement appears to be more straightforwardly erotic, focused on arousal and pleasure without a strong self-regulatory component. This distinction matters because a growing body of research on sexual behavior, echoing classic work on the functional motivations for sex, argues that people engage in sexual activity for reasons that extend well beyond pleasure, including coping with negative emotions, managing loneliness, or escaping boredom. The Low-Regulation profile demonstrates that a substantial share of teledildonics users sits squarely in the classic pleasure-driven camp.

The third profile, Standalone Toy Users, made up 22.6 percent of the sample and showed the lowest endorsement of technology integration as a motive. Consistent with that motivational indifference to connectivity, these users favored manual, non-interactive devices. Their presence in the dataset is intriguing: even within a customer base of a connected sex toy company, roughly one in five men reported using toys in ways that downplay the technological features that define teledildonics. This suggests that the purchase of a smart device does not guarantee its smart use, and that some consumers treat internet-connected toys as simply well-engineered conventional sex toys, choosing to ignore or rarely activate the remote and interactive capabilities that companies invest heavily in developing.

The smallest but perhaps most theoretically interesting class was the Tech-Integrated Regulators, comprising 8.9 percent of users. This group moderately to strongly endorsed all five motives simultaneously and almost always used teledildonics in conjunction with pornography. For these men, connected devices serve a constellation of functions at once: heightening arousal, promoting relaxation, compensating for a partner’s absence, relieving boredom, and satisfying an appetite for technological novelty. The near-universal combination with pornography in this group points to a highly integrated digital sexual script, in which interactive hardware, streaming content, and regulatory motives form a single, cohesive ecosystem of use. Whether such multi-motivated engagement carries any implications for sexual health or compulsivity is a question the authors flag for future research.

Beyond the motivational typology itself, the study examined how class membership related to sociodemographic characteristics, usage modalities, and sexual satisfaction. The researchers analyzed associations with variables such as age, sexual orientation, and relationship status, as well as usage frequency, concurrent pornography use, and the type of sex toy employed. This analytical strategy reflects a broader shift in sexology and technology adoption research: rather than asking whether people use a technology, investigators increasingly ask how, why, and in what relational context, recognizing that the same device can serve radically different purposes in different lives. The four profiles are therefore not merely descriptive curiosities but building blocks for theoretical models that connect sexual motivation, technology design, and intimate practice.

The authors emphasize that teledildonics practices are embedded in complex individual and relational contexts, shaped by far more than the pursuit of sexual pleasure. That conclusion carries practical weight. For designers, recognizing that a large share of users deploy connected toys as instruments of comfort and partner substitution rather than gadgetry argues for interfaces and features that acknowledge intimacy and companionship, not just interactivity. For public health professionals, the profiles suggest that tailored sexual health promotion, including messaging about safe use, privacy, and balanced engagement with digital sexual content, should be stratified by motivational profile rather than aimed at an undifferentiated mass of consumers. A one-size-fits-all approach risks missing the Solo Comfort Seeker who may be navigating loneliness, just as it may alienate the pleasure-focused Low-Regulation User who has no interest in therapeutic framing.

The study also sits within a rapidly expanding scholarly conversation about digital intimacy. Related work has examined sextech adoption across national samples, the role of technology-mediated sexual interaction in romantic relationships and attachment, the emergence of so-called digisexuality as a sexual identity, and the foundations of erobotics, the study of erotic machines. Teledildonics occupy a unique position in that landscape because they are tactile, interactive, and increasingly compatible with virtual reality and long-distance partnered play. As the devices proliferate, understanding the motivational architecture of their users becomes a prerequisite for evidence-based design standards, privacy protections, and clinical guidance. The dataset underlying the study has been made publicly available, an unusual and welcome transparency measure in a field where commercial funding is common; the company whose customers were surveyed supported recruitment and data collection, while the researchers report maintaining independent control over data access and analysis.

Several limitations warrant caution in interpreting the findings. The sample consisted of customers of a single teledildonics company, which may not represent the broader population of connected toy users, and the cross-sectional design captures a snapshot rather than trajectories of use over time. The self-reported motivational indicators, while carefully chosen, cannot exhaust the full range of reasons people might have for using such devices. Still, the four-profile solution offers a robust empirical scaffold for the next generation of research, including longitudinal studies, comparisons across manufacturers and platforms, and investigations of how these profiles shift across the lifespan or in response to relationship changes. What the study makes unmistakably clear is that the question of why men use connected sex toys has not one answer but four, and that the future of intimate technology will be written not by a single type of user but by a diverse public whose motives span comfort, pleasure, regulation, and the sheer fascination of machines that respond to touch.
