Title
Sexual satisfaction in people with spinal cord injury and their partners: an explorative study.
Objective
To investigate the determinants of sexual satisfaction among individuals with spinal cord injury and relative partners by assuming a bio-psycho-social perspective.
Setting
Online survey.
Methods
Thirty-eight individuals (22 individuals with SCI and their partners) were provided with an anonymous self-report questionnaire. Bio-psycho-social dimensions were investigated by using the Barthel Modified Index, Beck Depression Inventory-II, Short Form Health Survey (SF-36). Sexual attitudes of participants were assessed via the Multidimensional Sexual Self-Concept Questionnaire (Snell, 1993).
Results
While no differences were observed between individuals with SCI and their partners, women with SCI were overall more satisfied about their sexual life when compared to men with SCI. Coping strategies promoting self-efficacy and an active role in the sexual issues were predictive of Sexual Satisfaction in the couples of persons with SCI and their partners. No significant contribution was played by physical variables.
Conclusion
A tailored-made approach assessing the needs of both individuals with SCI and partners is a key aspect for effective sexual rehabilitation protocols. According to the needs and features of each couple, health professionals should drive individuals with SCI and partners to cope with their sexuality within a bio-psycho-social framework underlying it.

Introduction
People with a spinal cord injury experience a series of profound changes both on a physical level and on a psycho-social level [1, 2]. Although the recovery of sexual function has been acknowledged as a matter of great concern in individuals with SCI [1], this issue has been historically neglected when treating functional consequences after an SCI [3, 4].
In the past decades, sexuality treatment in individuals with SCI has been mostly approached by assuming a “biological” framework [3, 5, 6]. According to this approach, individuals with SCI would suffer from a sexual disability due to neurological dysfunctions preventing them from having sex according to the normal standard [7]. Only recently attention has been paid to this topic in both healthy and disabled persons by assuming a holistic approach to health—i.e., accounting for not only biological but also psycho-social variables [8, 9]. According to bio-psycho-social models, health arises from continuous and dynamic interactions between biological, psychological and social factors [10, 11]. Interestingly, yet in 1975, the World Health Organization [12] focused on a holistic approach to sexual health as a fundamental right to be guaranteed to all individuals, recognizing it as the experience of a continual state of physical, psychological, and sociocultural well-being in terms of sexuality [13, 14] More recently, Firestone et al. [15] defined sexuality in a broad sense, affirming that it “[…] encompasses all the feelings, attitudes, and behaviors that contribute to a person’s sense of being a man or a woman both publicly and privately. Healthy sexuality represents a natural extension of affection, tenderness, and companionship between two people”. Interestingly, this definition further emphasizes the experience of the intimate partner and thus the couple dimension.
A proper investigation of sexual health and satisfaction should thus go beyond the perspective of individuals with SCI, including also feelings and experiences of their sexual and emotional partners. With this respect, only few studies have explored the impact that SCI-related changes may have on the individual and her/his intimate partner [16,17,18,19]. These studies have nonetheless highlighted the relevance to sexual satisfaction of emotional well-being, body image and relationship with the partner besides physical functioning. Indeed, after an SCI, the decrease in personal autonomy and dependence on others in self-care can lead to changes in roles—this possibly altering the sexual dimension [20]. Given the relevance of sexual health within a couple, both individuals with SCI and their partners might experience a change in their general well-being [21, 22]. However, no study tried to explore how sexuality is experienced and perceived in a couple with an individual with SCI, and which factors can affect the levels of sexual satisfaction. This study thus aimed at exploring the determinants of sexual satisfaction in both persons with SCI and their respective intimate partners by addressing both physical and psycho-social predictors.
Materials and methods
Participants and procedure
Thirty couples were recruited in the north-east part of Italy from 2017 to 2018. Exclusion criteria for both individuals with SCI and their partners were other neurological pathologies, psychiatric and internal conditions. Questionnaires were distributed via e-mail and returned online (30–40’ completion time).
Response rate was 63.3% (38 out of 60). Twenty-four were individuals with SCI (9 females), and 16 partners (12 females) enrolled the study. Among those who did not answer the questionnaire, 19% were males and 7% females. Participants’ background and psychometric measures are displayed in Table 1. No economic incentive was provided for participations; responses were anonymous. The study was approved by the Ethical Committee (nr. 478/ORAS, 2018) of the local public Health System (ULSS 2 Treviso). All participants provided written informed consent to participation. Data were treated according to current regulations.
Materials
Following a bio-psycho-social approach, physical and psycho-social dimensions were self-reportedly explored along with sexuality (see Table 2).
Biological measures
Motor-functional outcome was assessed via the Barthel Modified Index (BMI) [23, 24]. The Italian BMI is internally consistent (Cronbach’s α = 0.94) and comes with optimal test-retest reliability evidence (ICC = 0.98) in clinical populations. Moreover, the BMI proved to be feasible in population with SCI, as optimally converging with the Functional Independence Measure (a gold-standard measure of ecological functional outcome) [25]. The Physical Functioning subscales of SF-36 (PF) [26,27,28] was also considered in order to evaluate physical measures. Within the Italia population, the PF shows optimal internal consistency (Cronbach’s α = 0.93) and construct validity toward the General Health (GH) scale of the SF-36 [28].
Psycho-social measures
Depression levels were assessed through the Beck Depression Inventory-II (BDI-II) [29, 30] and the psychological subscales of SF-36 (Vitality, VT; Role emotional, RE; Mental health, MH). Usability in individuals with SCI of both the BDI-II and SF-36 psychological subscales has been shown [31, 32]. The Italian BDI-II [30] shows optimal internal consistency (Cronbach’s α = 0.8), convergent validity toward gold-standard measures of depression- and anxiety-related measures, a solid bi-factorial structure (RMSEA = 0.055; CFI = 0.92) and optimal diagnostic accuracy (AUC = 0.88). VT, RE and MH scales of the SF-36 show adequate internal consistency (Cronbach’s α = 0.78, 0.85 and 0.85, respectively) and construct/criterion validity toward the GH scale. [28].
Social functioning was assessed by the Social Function (SF) subscale of the SF-36. The SF scale show adequate internal consistency (Cronbach’s α = 0.77) and construct/criterion validity toward the GH scale [28].
Sexuality measures
Sexuality was investigated through the Multidimensional Sexual Self-Concept Questionnaire (MSSCQ) [33, 34]. MSSCQ is a self-report, Likert-item questionnaire measuring 20 facets of the sexual self-concept. Scores on each scale range from 5 to 25; high scores corresponding to higher levels of the construct. The original MSSCQ was translated into Italian. From the original questionnaire, two measured variables excluded were ruled out: Motivation to avoid risky sex (as we investigated sexuality in stable couples) and Sexual self-problem prevention (as it would have been difficult to disentangle general sexual self-problem prevention from issues deriving from SCI).
Sexual satisfaction was measured with the Sexual Satisfaction subscale of the MSSCQ [33, 34]. This subscale comprises five items—an example of which is “I am satisfied with the way my sexual needs are currently being met.” and showed optimal internal consistency in both females and males individuals (both Cronbach’s α = 0.91) within the original normative study [34].
Further ad hoc sexuality Likert-like measures were constructed in order to explore other variables more focused on SCI condition. Each variable was tested by means of two main questions once the participants completed MSSCQ. The subscales included:
-
Fertility: the importance of fertility in their sexual activity.
-
Other forms of sexuality: the importance of exploring other forms of sexuality apart from physical contact.
-
Satisfaction with the partner before and after the SCI.
-
Only for individuals with SCI: the decreasing of sexual intercourse after the SCI.
Statistical analyses
Normality and homoscedasticity assumptions were checked on raw variables by assessing skewness and kurtosis values (judged as indexing abnormalities if ≥|1| and |3|, respectively) [35].
Since sexual satisfaction was judged as meeting linear model assumptions, effects of Group, Sex and Length of Couple Relationship were simultaneously tested by means of a between-subject analysis of variance (ANOVA).
Consistently, in order to identify the best set of predictors of sexual satisfaction in individuals with SCI and Partner Group, stepwise multiple linear regression (MLR) analyses were performed separately for both groups. All motor-functional, psycho-social and (other) sexuality measures were entered as predictors in both MLRs, with the exception of Length of Couple Relationship (before vs. after the injury). Collinearity was inspected for by assessing variance inflation factor (VIF) and tolerance index (judged as abnormal if >10 and 0.1<, respectively) [36]. Analyses were performed via SPSS 27 [37]. Significance level was set at α = 0.5.
Results
Bio-psycho-social and sexuality measures of participants are summarized in Table 2.
ANOVA revealed no main effects with the exception of Length of Couple Relationship (F(1,31) = 12.285; p = 0.001; η2 = 0.284): individuals who started a relationship after the injury (x̄ = 3.25; SE = 0.28) were more sexually satisfied than those who already had it before the event (x̄ = 2.16; SE = 0.12). Furthermore, a significant two-way Group*Sex interaction was detected (F(1,31) = 4.736; p = 0.037; η2 = 0.133) (see Fig. 1): its decomposition by means of post hoc, Bonferroni-adjusted comparisons showed that, within individuals with SCI only, sexual satisfaction was higher for females (x̄ = 3.29; SE = 0.33) than for males (x̄ = 2.25; SE = 0.27).
No other significant terms have been yielded.
Stepwise MLR for Partner Group proved that the best model (R2 = 0.82; F(2,11) = 25.54; p < 0.001) encompassed Sexual Depression (β = 0.62; t = −4.25; p = 0.001) and Chance/luck Sexual Control (β = −0.425; t = −2.92; p = 0.014). With regard to individuals with SCI, Sexual Self-efficacy (β = 0.829; t = 1.99; p < 0.001), decreasing of sexual intercourse after SCI (β = −0.34; t = −4.77; p < 0.001), years of education (β = 0.34; t = −5.51; p < 0.001), Satisfaction with partner before SCI (β = 0.26; t = 4.09; p = 0.001) and Sexual Fear/Apprehension (β = 0.26; t = 3.77; p = 0.002) proved to be the best set of predictors (R2 = 0.95; F(5,14) = 57.21; p < 0.001). In both models, no abnormal VIF/tolerance index was noted.
Given the theoretical juxtaposition between the constructs underlying Sexual Self-Efficacy and Chance/Luck Sexual Control [33], their association was further explored in the two groups via Spearman’s coefficient (due to small sample sizes). No association was found between Sexual Self-Efficacy and Chance/Luck Sexual Control in Partner Group (rs(16) = −0.44; p = 0.086), where the two variables were inversely correlated in individuals with SCI (rs(22) = −0.44; p = 0.038).
Discussions
Sexual satisfaction is a complex and dynamic experience that is subjected to physical, psychological and relational changes after an acquired SCI. While many attempts have been made to deal with sexual issues from the medical perspective, few research works tried to deepen the sexual issue by assuming a double perspective—that of individuals with SCI and relative partners. In this respect, the present work provides with preliminary evidence suggestive of different determinants affecting sexual health in individuals with SCI and their partners—although no differences were detected between-group in sexual satisfaction.
First, we found no differences in perceived sexual satisfaction between individuals with SCI and partners, while sex differences were detected—with females exhibiting higher levels of sexual satisfaction.
Second, in line with the literature [38, 39], couples formed after SCI showed higher levels of sexual satisfaction than couples formed before. It may be hypothesized that meeting the partner after SCI might allows establishing a de novo balance within the relationship, in which SCI is represented as a “normal” condition, rather than a modification of a previous one [39]. The couple would practice a wider range of habits during sexual practice without being compared to the previous condition, thus sharing new common future intercourses in which SCI does not determine a restorative couple but simply a factual reality on which a new relationship is being created [39, 40].
Interestingly, in both groups, no biological variables (i.e., associated to levels of motor dimension and functional independence) were found to affect sexual satisfaction when tested along with psycho-social predictors—this further endorsing that sexual health should be both clinically and experimentally addressed within a bio-psycho-social framework in disabilities [41,42,43]. However, it is worth noting that individuals with SCI participating to this research were recruited after at least 1-year pass the inpatient rehabilitation stage. In line with previous findings, since the biological dimensions and physiologically related sexual changes are usually a target priority of persons with SCI during the inpatient rehabilitation phase [20], it can be hypothesized that participants with SCI paid more attention to other variables than the biological ones given their ability to deal with them during the inpatient phase [20, 44].
By contrast, as suggested in the literature [45], the vast majority of sexual satisfaction determinants were mostly related to personal and sexual dimensions. However, strikingly, no overlap was found between the predictors of sexual satisfaction in individuals with SCI and their partners: while Chance/Luck Sexual Control was found to be predictive of sexual satisfaction in the partner group, Sexual Self-efficacy predicted sexual satisfaction for individuals with SCI. These findings suggest that different perspectives are adopted by individuals with SCI and their partners when dealing with sex-related issues and re-organizations of couple dynamics.
On the one hand, individuals with SCI seem to rely on a personal capacity of dealing with sexual issues depending on their condition. According to the literature, it has been demonstrated that individuals who are inclined to adopt active coping styles (e.g., believing they have a strong capacity to influence the direction of their lives [46, 47], knowing how to use different strategies in a flexible way [47, 48]) can achieve more positive ways of adapting to SCI [49,50,51]. Interestingly, as SCI is a clinical condition that globally affects an individual’s life, our data seem to highlight and confirm the importance of promoting the capacity of an active coping and adjustment when dealing with a SCI and sex-related practical issues to achieve high levels of sexual satisfaction [17]. Indeed, SCI has a profound impact on the body and its function [52], also being able to increase psychological distress impacting sexuality. Individuals with SCI find themselves experiencing a transition from a “known” body, in which every part of it was framed within a pattern, to an “unpredictable” body, which no longer reacts to the function of the former [48]. In this transition, a satisfactory level of sexual satisfaction would be reached by individuals with SCI when they become able to learn and develop a suitable capacity to recognize and manage the consequences of a SCI (i.e., bladder, bowel, spasticity, neuropathic pain, the inability to achieve reflex arousal and orgasm; [52]) affecting their sexuality. In this challenging process, health care professionals should pay attention to sexuality in order to help patients integrate different aspects of their body by specifically addressing the sexual dimension [17, 53,54,55]. In line with previous records, another predictive variable associated with satisfactory sexual life was the level of education of individuals with SCI [17]. First, higher levels of educational attainment might help individuals with SCI improve their problem-solving and self-efficacy thus leveraging their role in their sexuality (as discussed above); second, higher educational levels might promote more satisfactory social and occupational status—thus suggesting the importance of psycho-social inclusion after SCI when dealing with sexuality [17, 45].
The quality of a relationship was another key factor determining high levels of sexual satisfaction, highlighting the importance of considering such an issue not a personal one of individuals with SCI but rather something to share with the partner [17, 20]. As suggested by Lo Piccolo [56], the responsibility for sexual dysfunction must be shared, since intercourse takes place within the context of a pair relationship [57]. In this way, the optimal sexual functioning for the couple would depend on the willingness of both partners to take joint responsibility for an adequate sexual adjustment, playing together an active role in managing their sexuality.
Similar results were obtained for the partner group. Indeed, we found that lower levels of Chance/Luck sexual control were predictive of sexual satisfaction. In other words, in line with the literature [39], the more partners experience inclusion and responsibility in sexual life, the more satisfactory their sexual experience will be. Notably, the partner of an individual with SCI has been traditionally seen as the “caregiver”—with the dramatic consequences of such a perspective. Indeed, a switch from the role of an intimate partner may come with the risk of considering the disabled person more as a patient than as a partner [21, 58]. For partners, taking the role of a “passively” assisting caregiver who deal with motor impairments, bladder and bowel management without actively changing their condition, might greatly contribute to placing psychological barriers regarding the desire to resume a sexual life with one’s partner thus developing disappointment, anger, sadness and loss of intimacy [18, 58]. The physical limitations of the partner with SCI can also have a negative impact on the sexual desire of the non-disabled intimate partner. In addition, the partner may be afraid of having sexual intercourse with the partner with SCI, fearing that further injuries will occur during sexual intercourse [19, 59]. Thereupon, helping the partner develop emotional and physical closeness with the person with SCI, as well as to share and actively explore with her/him new forms of sexuality, can be a key predictive factor to reach a satisfactory sexual life [16, 19, 40].
Overall, in line with the literature, biological factors—such as the physical status and functional independence—did not significantly predict the perceived sexual satisfaction in the two groups, further suggesting the multidisciplinary determinants of this construct, going beyond a medical issue [17, 22, 45, 60].
Implications for sexual rehabilitation programs after spinal cord injury
According to our results, sexual rehabilitation programs for individuals with SCI and relative partners must go beyond biological aspects [61], broadening the intervention to factors focusing on the diversity and uniqueness of each individual living in their own reference psycho-social context [62, 63].
Indeed, individuals with SCI and partners must learn to redefine their concept of sexuality by adapting it to a new situation. In line with the results here reported, health professionals should drive individuals with SCI to “understand” their new body and learn to manage it within different contexts, including the sexual one. At the same time, health professionals should pay attention to the partners too, discouraging them to assume the role of caregiver when not necessary (i.e., related to the management of SCI issues), promoting the role of intimate partner as well. Sexual rehabilitation programs should thus help the couples adopt active adjustment processes, encouraging a shifting of the issue from “my problem” to “our problem” [64]. In this way, sexual health of the couple takes place from the willingness of both partners to take responsibility for sexual adjustment along bio-psycho-social dimensions as well [65].
Study limitations and future directions
Our study was culture-and language-specific (Northern part of Italy). Given the peculiar socio-political tradition and religious heritage of Italy, it would be insightful to examine how sexual satisfaction is perceived and experienced in individuals with SCI and their partners who come from cultures, religions, traditions other than Italian and, more broadly, Western ones. It is also worth noting that only heterosexual participants took part in the study, thus future investigation might explore the sexual satisfaction perceived in homosexual couples. Moreover, sexual satisfaction was explored in couples in which only one person has an SCI: how sexuality is perceived in couples in which both partners have an SCI might be addressed in future works.
A major limitation of this study was that the MSSCQ was adapted to Italian without any standardization process (i.e., back-translation). Therefore, an investigation is needed which focuses on the Italian adaptation of the MSSCQ, as well as on exploring its psychometric properties in an Italian population sample. In addition, bio-psycho-social dimensions were explored by using a specific corpus of instruments, but other questionnaires might help to better define the role of such dimensions underlying the sexual satisfaction.
In spite of the above limitations, our investigation emphasizes the importance of an active role played by both individuals with SCI and their partners in the quality of their sexual life. Starting from these findings, future investigation would attempt at improving tailored sexual rehabilitation programs during both the inpatient and the outpatient phases of rehabilitation for individuals with SCI and their partners, taking into account its medical and clinical condition, psychological status and socio-relational dynamics in the couple.
