Validation of the International Index of Erectile Function (IIFE) for use in Brazil

Sexuality and sexual dysfunction in patients with psoriatic arthritis: A cross-sectional study

OBJECTIVE

Psoriatic arthritis (PsA) is a chronic inflammatory disorder affecting the joints, skin and entheses. Despite the importance of the topic, few studies have investigated the association between PsA and sexual function. The purpose of this study was to assess sexuality and the prevalence of sexual dysfunction (SD) in patients with PsA.

METHODS

This was an observational, cross-sectional single-center study on 23 PsA patients (male=12; female=11) evaluated with 2 male questionnaires (MSQ= Male Sexual Quotient, and IIEF=International Index of Erectile Function) and 2 female questionnaires (FSQ= Female Sexual Quotient, and FSFI=Female Sexual Function Index) validated for Brazilian Portuguese, in order to determine changes in sexual function. Clinical parameters, musculoskeletal activity and skin activity were also analyzed to identify factors associated with SD.

RESULTS

The mean age was 52.1±9.7 years (males) and 49.1±9.6 years (females). Clinically, the patients had low skin and peripheral joint disease activity or were in remission. The mean time of PsA was 10±6.2 years, and 65.2% had a steady sexual partner. The mean MSQ score was 75.8±16.8. The prevalence of SD was 91.7% in men (IIEF), with a predominance of mild SD. The mean FSQ score was 64.9±24.1. The prevalence of SD was 72.7% in women (FSFI), with low domain scores. Also, a significant association was found between female age and total and domain-specific FSFI scores. PASI (Psoriasis Area and Severity Index) and the general satisfaction domain (IIEF) were significantly correlated.

CONCLUSION

This study found a high prevalence of SD in PsA patients. Age had a negative impact on female sexual function. Physicians need to be more aware of SD in this population to provide early multidisciplinary treatment and minimize the impact of the disease on the quality of life of patients and their partners.

Web-Based Emotion Regulation Training for Sexual Health: Randomized Controlled Trial

BACKGROUND

Effective emotional regulation (ER) skills are important for sexual function, as they impact emotional awareness and expression during sexual activity, and therefore, satisfaction and distress. Emotion regulation interventions may offer a promising approach to improve sexual health. Web-based emotion regulation may be a therapeutic strategy for men and women with sexual health concerns. Nevertheless, there is a scarcity of intervention trials investigating its effects in this context, much less using the internet.

OBJECTIVE

This study aims to investigate the effects of a web-based emotion regulation training program for sexual function in both men and women.

METHODS

The participants were recruited based on their self-reported sexual problems, which for men was defined by a score of <25 on the International Index Erectile Function (IIEF) and for women by a score of <26.55 on the Female Sexual Function Index (FSFI). The final sample included 60 participants who were randomized to either a web-based emotion regulation training for sexual function or to a waitlist control group. The treatment consisted of an 8-week web-based emotion regulation training for sexual function. The participants were assessed at baseline, post intervention, and the 3-month follow-up.

RESULTS

Of the 60 participants included, only 6 completed all 3 assessment points (n=5, 20% in the treatment group and n=1, 5% in the waitlist control group) after receiving the intervention. At follow-up, there were no significant differences between groups in any measure. Among the intervention completers, large-to-moderate within-group effect sizes were observed between the assessment points on measures of emotion regulation, depression, lubrication, orgasm, thoughts of sexual failure, and abuse during sexual activity. The adherence rate was very low, limiting the generalizability of the findings.

CONCLUSIONS

Participants who completed the intervention showed improvements in both sexual function domains and emotion regulation. Nonetheless, due to a high dropout rate, this trial failed to collect sufficient data to allow for any conclusions to be drawn on treatment effects.

Heart Failure and Erectile Dysfunction: a Review of the Current Evidence and Clinical Implications

PURPOSE OF REVIEW

Heart failure (HF) and erectile dysfunction (ED) are two common conditions that affect millions of men worldwide and impair their quality of life. ED is a frequent complication of HF, as well as a possible predictor of cardiovascular events and mortality. ED deserves more attention from clinicians and researchers.

RECENT FINDINGS

The pathophysiology of ED in HF involves multiple factors, such as endothelial dysfunction, reduced cardiac output, neurohormonal activation, autonomic imbalance, oxidative stress, inflammation, and drug side effects. The diagnosis of ED in HF patients should be based on validated questionnaires or objective tests, as part of the routine cardiovascular risk assessment. The therapeutic management of ED in HF patients should be individualized and multidisciplinary, considering the patient's preferences, expectations, comorbidities, and potential drug interactions. The first-line pharmacological treatment for ED in HF patients with mild to moderate symptoms (NYHA class I-II) is phosphodiesterase type 5 inhibitors (PDE5Is), which improve both sexual function and cardiopulmonary parameters. PDE5Is are contraindicated in patients who use nitrates or nitric oxide donors for angina relief, and these patients should be advised to avoid sexual activity or to use alternative treatments for ED. Non-pharmacological treatments for ED, such as psychotherapy or couples therapy, should also be considered if there are significant psychosocial factors affecting the patient's sexual function or relationship. This review aims to summarize the most recent evidence regarding the prevalence of ED, the pathophysiology of this condition with an exhaustive analysis of factors involved in ED development in HF patients, a thorough discussion on diagnosis and management of ED in HF patients, providing practical recommendations for clinicians.

The Role of Emotion Regulation Strategies for Sexual Function and Mental Health: A Cluster Analytical Approach

We investigated distinct profiles in emotion regulation strategies (reappraisal and suppression) and their associations with sexual function and mental health. The online survey sample consisted of 5436 adult participants. The gender stratified cluster analysis resulted in a four-cluster solution for both men and women. Better sexual function and mental health scores were found for participants with high cognitive reappraisal and low expressive suppression. High expressive suppression was associated with higher anxiety and depression and worse sexual function. Sexological care should take into account the assessment of emotion regulation abilities and emotion regulation training interventions to support reappraisal strategies.

Factors Associated with Satisfaction with Male Genital Self-Image in Brazil

Male genital self-image (GSI) refers to how men feel about their genitals. Studies suggest that GSI is influenced by several psychosocial and physical factors, such as frequency of sexual activities, anxiety, and sexual dysfunctions. In Brazil, no studies have investigated the factors associated with satisfaction with male GSI. This is a cross-sectional and online study conducted with Brazilian men over 18 years of age. The Male Genital Self-Image Scale (MGSIS), Body Appreciation Scale-2 (BAS-2), and International Index of Erectile Function (IIEF) were used. Body appreciation and frequency of sexual activity were included as confirmatory variables and other variables were explored as factors associated with GSI. Data were analyzed by binary logistic and multiple linear regression, according to the MGSIS cut-off point for satisfaction with male GSI and total score of MGSIS, respectively. A total of 1,235 men (M = 26.14, SD = 7.28 years) participated in the study. The mean of the total MGSIS score was 23.02 (SD = 4.45; absolute range, 7-28) points, with 62.11% of men being classified as satisfied with GSI. Men satisfied with GSI were more likely to have a partner, higher body appreciation, lower body mass index (BMI), and not have phimosis (excess skin covering the penis, making it difficult to expose the glans). Satisfaction with GSI of Brazilian men was associated with relationship status, body appreciation, BMI, and phimosis.

The Sexual Function, Desire, and Satisfaction of Couples during the Outbreak of COVID-19 in Qazvin

Background

The COVID-19 pandemic has significantly affected the lives of the community. The resulting social constraints and the physical and psychological consequences are also expected to affect sexual health. The present study aims to determine the status of sexual function, desire, and satisfaction of couples during the outbreak of COVID-19.

Materials and Methods

This is a descriptive online cross-sectional study on 400 married individuals living in Qazvin, Iran, from October 15 to November 12, 2020. The multi-stage random cluster method is used for sampling. The following questionnaires have been used for data collection: Female Sexual Function Index (FSFI), Rosen male sexual function, Larson's sexual satisfaction, and Hurlbert Index of Sexual Desire (HISD). The questionnaires were sent to participants through online messengers. The obtained data were analyzed by SPSS software (v25).

Results

The findings show that only 19.20% of study participants had sex three or more times a week. Most of the participating women (56.90%) had sexual dysfunction, while most men (64.30%) had proper sexual function. Also, the majority of participants had moderate sexual desire (46%) and high sexual satisfaction. The primary predictors of sexual dysfunction in men and women during the outbreak of COVID-19 were "employment in health centers" (B = -9.34, p = 0.007) and "spouse working in health centers" (B = -6.16, p = 0.007), respectively.

Conclusions

The psychological burdens of the COVID-19 pandemic and resulting measures, such as prevention protocols, affect couples' sexual relations. Therefore, interventions are necessary to improve the quality and health of the sexual life of couples.

What are the Main Risk Factors Associated with Erectile Dysfunction in the Elderly? A Cross-Sectional Study of 2436 Brazilian Elderly Men

Background

Erectile dysfunction (ED) is a multifactorial medical disorder often neglected in clinical practice between elderly men, defined as the inability to achieve and/or maintain a penile erection sufficient for satisfactory sexual intercourse and a common clinical entity among men and associated with impaired quality of life and cardiovascular diseases in elderly men. The aim of this study is to evaluate the association between ED and clinical, demographic and behavioral parameters in elderly men.

Methods

A total of 2436 males aged 60 years and over who participated in the health screening between January 2008 and December 2018 were included in this study. Laboratory exams, clinical and behavior profiles were analyzed. Logistic regression models were used.

Results

Men with ED were older (65.87±5.49 vs. 63.85±4.05 years old. p<0.001), higher prevalence of physical inactivity (23.8 vs. 19%, p = 0.039) and had a higher body mass index (BMI; 28.36±4.06 vs. 27.72±3.89 kg/m². p<0.001) than men without ED. The multivariate model shown that hypertension (p = 0.001), diabetes mellitus (p<0.001), lower urinary tract symptoms (LUTS), depressive symptoms (p<0.001) and age (p<0.001), were strongly associated with ED.

Conclusion

The main risk factors associated with ED in elderly men were hypertension, diabetes mellitus, LUTS, depressive symptoms and age.

The Spanish Version of the International Index of Erectile Function: Adaptation and Validation

BACKGROUND

The International Index of Erectile Function (IIEF) is a widely employed questionnaire in urology to assess erectile dysfunction (ED) in both clinical research and practice.

OBJECTIVE

To translate and culturally adapt the Spanish version of the International Index of Erectile Function (IIEF) and to analyze its psychometric properties in Spanish men with erectile dysfunction (ED).

METHODS

Firstly, direct and reverse translations were performed. Secondly, a pilot study was carried out on 23 patients with the lowest possible education level without being illiterate. Finally, 170 participants completed the IIEF. Test-retest reliability, internal consistency and construct validity (exploratory factor analysis) were assessed. Concurrent and divergent validity were evaluated with the Hospital Anxiety and Depression Scale (HADS) and the 12-item Short-Form Health Survey (SF-12), respectively. Discriminant validity (with and without anxiety or depression) was calculated using a receiver-operating characteristic curve analysis.

RESULTS

High internal consistency (Cronbach's alpha = 0.968, total score) and moderate-to-excellent test-retest reliability were found. The factor analysis showed a two-factor structure (explained variance of 77.34%). Significant correlations of the IIEF total score (p < 0.01) and domains (p < 0.05) with HADS anxiety and depression scores were observed (concurrent validity), while non-significant correlations with SF-12 physical and mental summary scores were found (divergent validity). The IIEF total score could discriminate between participants with and without anxiety (p < 0.05) and depression (p < 0.01), with an optimal cut-off point of <39.50 for both anxiety (48.30% sensitivity and 78.75% specificity) and depression (50.00% sensitivity and 81.01% specificity).

CLINICAL IMPLICATIONS

The psychometric properties of the IIEF have not been analyzed in Spanish people to date. Strengths and Limitations: The Spanish version of the IIEF was shown to be capable of discriminating between men with erectile dysfunction with and without depression or anxiety. There are some limitations to this study that should be noted. It was conducted on Spanish participants, and, thus, it should be employed with caution in other Spanish-speaking countries. This study was carried out on a selected population, and, therefore, the generalizability of its results to other populations might be limited. Moreover, a large majority of the participants (89.41%) had secondary or higher education. Future studies should be performed on a more general population with a varied geographical and educational background.

CONCLUSIONS

The Spanish IIEF is a valid and reliable instrument for assessing erectile function among Spanish men with ED.

Interaction between the impact of the Coronavirus disease 2019 pandemic and demographic characteristics on sexual/erectile dysfunction in Latin America: cross-sectional study

Aim:

Our objective was to investigate whether there is an interaction between the COVID-19 pandemic, demographic characteristics and erectile/sexual (E/S) function in individuals from Latin America.

Materials and Methods:

Cross-sectional study which included Latin American individuals over 18 years old, recruited through social media and interviewed between July and August 2020 by online surveys (Google Forms) in Portuguese and Spanish languages. The E/S function was evaluated through the following questionnaires: Simplified International Index of Erectile Function (IIEF-5) and Female Sexual Function Index (FSFI); while post-traumatic stress disorder (PTSD) triggered by the COVID-19 pandemic was assessed through the Impact of Event Scale Revised (IES-R). The data was analyzed by T Student, bivariate and multivariate logistic regression, with significance determined by the Wald test (p<0.05), using the R software v4.0.

Results:

Out of the 2016 individuals that responded to the survey, 1986 were included and 743 of them presented E/S dysfunction. PTSD occurrence was greater among people with E/S dysfunction when compared to those without E/S dysfunction, in the total score (males: IES-R=26.54[±19.17] and females: IES-R=35.92[±19.25]) and also in the three domains. It was found that those who do not live with a partner were 74% more likely to have E/S dysfunction, but living with a partner during the pandemic had a greater impact on E/S function.

Conclusion:

A negative interaction between the impact of the COVID-19 pandemic and erectile/sexual function of the Latin American population was observed, with greater implications among the individuals who live with their partners.

Sexual function and sexual quality of life in men with genital warts: a cross-sectional study

BACKGROUND

Human papillomavirus is the most common sexually transmitted infection, usually passing from one person to another after the first sexual activity. Infection with this virus and the occurrence of genital warts (GWs) could have several effects on patients' health. This study was performed to evaluate the sexual function and sexual quality of life (SQOL) in men with GWs.

METHODS

This cross-sectional study was conducted from September 2019 to March 2020 with a sample size of 105 men with GWs in the dermatology clinic of Shahid Faghihi Hospital in Shiraz University of Medical Sciences, Iran. Data were collected using a demographic questionnaire, the International Index of Erectile Function (IIEF), and the Sexual Quality of Life-Men (SQOL-M) questionnaires and analyzed by descriptive and inferential tests with SPSS software version 22.

RESULTS

The mean score for overall sexual function in men was 48.50 ± 8.89. About 35.2% of men had overall sexual dysfunction (SD). The highest disorder rate was related to the erection domain (85.7%), and the lowest was related to the desire domain (5.7%). In the erection domain, most men (54.3%) experienced mild to moderate erectile dysfunction. The mean score for SQOL-M was 38.36 ± 14.47, and 56.2% of them had a good SQOL.

CONCLUSIONS

GWs affected men's erection more than the other sexual function domains. SD in men with GWs has a significant impact on their SQOL and ED was associated with impaired SQOL. Therefore, it is recommended to pay more attention to SD screening alongside SQOL assessment of men with GW.

Sexuality Assessment of the Brazilian Population: An Integrative Review of the Available Instruments

This paper provides an integrative review of psychometric instruments targeting sexual function and clinical measures of sexuality available to the Brazilian population. Our aim was to summarize the existing measures, indicating current development needs related to the quality of psychometric evidence, research design and untapped theoretical ground that could be relevant for clinical practice and research in sexuality. Electronic databases were searched. Additional records were found through a manual search. The general search terms and operators were (scale OR inventory OR questionnaire) AND (validation) AND (sexual beliefs OR sexuality OR sexual behavior OR sexual function OR sexual satisfaction) AND (Brazil or Brazilian). The results indicate a total of 18 developed or transculturally adapted and/or validated scales and questionnaires available in Brazilian Portuguese, covering sexual dysfunctions and clinical measures. Despite development, adaptation and validation efforts, there is a critical need for better psychometric and sampling strategies as well as norms for the clinical interpretation of test results. Ecological validity is also a challenge. At present, sexual assessments in Brazil offer some useful information, but reaching the applied clinical field remains a challenge.Supplemental data for this article is available online at https://doi.org/10.1080/0092623X.2022.2035869 .

Splenectomy is associated with sexual dysfunctions and decreased libido

The removal of the spleen due to disease or trauma may be followed by disorders due to the asplenism, including immunodeficiency, hematological and metabolic diseases, mainly dyslipidemia, which can lead to sepsis, pulmonary embolism and early death. Although patients frequently report sexual disinterest after splenectomy, this feature has been experimentally studied only in a translational investigation performed by the same group of this work. To study libido and other sexual functions after the complete removal of the spleen in humans. This study was performed on 60 healthy adults, 30 men and 30 women, after more than 1 year of total splenectomy to treat isolated splenic trauma. The International Index of Erectile Function was applied to men and the Female Sexual Function Index to women. The analysis compared the responses obtained in the periods before and after the splenectomy. Laboratory tests with hematological and biochemical analyses, including sex hormones, were performed in all patients. The pre- and postoperative results were compared in each group using the paired t-test, with each patient being his or her own control and with significance to p < 0.05. A decrease in libido and an increase in sexual dysfunction was observed after splenectomy in all men and women, p < 0.001. All postoperative laboratory tests showed normal values in both genders. Asplenia is associated with a marked decrease in libido and intense sexual dysfunction in both men and women, with normal hematological and biochemical laboratory tests, including hormonal exams.

Translation validity and reliability of the Indonesian version of the 5-item International Index of Erectile Function (IIEF-5)

OBJECTIVE

This study aimed to translate the IIEF-5 questionnaire into Indonesian and perform a validity and reliability assessment of the translated instrument.

MATERIAL AND METHODS

A methodological study on 106 male outpatients, recruited consecutively, was carried out in a tertiary hospital in Surabaya, East Java from January to March 2020. This study was conducted in two stages: translation and validation. Two independent sworn translators performed a forward and backward translation of the first draft. The final version was synthesized by a team of experts comprised two urologists and another sworn translator. The validity of the questionnaire is determined through a Pearson correlation analysis. Cronbach's a internal consistency measurement was used to assess its reliability. Interrater reliability between the patient and the physician was measured using the Cohen's j coefficient.

RESULTS

Pearson's "r" value is significantly higher than the critical value table and indicates a high to a very high level of validity based on Guilford's interpretation (r ¼ 0.70-1.00). A good internal consistency is shown by the Cronbach's a coefficient value (a ¼ 0.828). An almost perfect agreement between the patient's results and the assessment made by the physicians is shown by the Cohen's j coefficient value (j ¼ 0.879, P < .001).

CONCLUSION

The Indonesian IIEF-5 is a valid and reliable patient-reported outcome measure for evaluating erectile dysfunction in the literate middle-aged and older adult male population in Indonesia.

A randomized controlled trial of an Internet-based emotion regulation intervention for sexual health: study protocol

Introduction

Emotion regulation difficulties have been associated with mental disorders and sexual dysfunctions. Traditional face-to-face transdiagnostic emotion regulation interventions have shown positive results for emotional and personality disorders. Only recently have the effects of these interventions on sexual health started to be investigated. Internet-delivered psychological interventions have several advantages over face-to-face interventions, such as cost-effectiveness, accessibility, and suitability for people who experience shame because of their stigmatized problematic behaviors and those who avoid seeking help. The aims of the SHER 2—TREpS (Portuguese acronym for Emotion Regulation training for sexual health) project are as follows: (a) determine the efficacy of an Internet-based emotion regulation intervention for sexual health and sexual satisfaction and (b) explore the effects of the intervention on (1) emotion regulation skills, (2) mental health, and (3) sexual self-perception.

Methods and analysis

The study will use a randomized controlled trial design. Eligible participants will be randomly allocated to one of two groups: intervention (Internet-based emotion regulation training) or waitlist control. Assessments will take place before the start of the trial, at the end of the trial, and at 6-month follow up, after which participants assigned to the waitlist control condition will receive the same intervention. Primary outcomes include sexual function and satisfaction and secondary outcomes self-report measures of depression, anxiety, difficulties in emotion regulation, and sexual self-perception. This intervention study is financed by the Luxembourg National Research Fund (FNS).

Ethics and dissemination

Ethics approval was obtained from the Ethics Review Panel of the University of Luxembourg. Findings will be disseminated via peer-reviewed publications and conference presentations.

Pelvic floor muscle training and electrical stimulation as rehabilitation after radical prostatectomy: a randomized controlled trial

[Purpose] To investigate the effect of electrical stimulation and pelvic floor muscle training on muscle strength, urinary incontinence and erectile function in men with prostate cancer treated by radical prostatectomy. [Subjects and Methods] One hundred twenty-three males were randomized into 3 groups 1 month after RP: (G1, n=40) control; (G2, n=41) guideline: patients were instructed to perform three types of home exercises to strengthen the pelvic floor and (G3, n=42) electrical stimulation: patients in this group were also instructed to perform exercises as group G2, and also received anal electro-stimulation therapy, twice a week for 7 weeks. The primary outcome assessment was based on the measurement of the recovery of pelvic floor muscle strength between groups. Secondary outcomes were: 1 hour Pad Test, ICIQ-SF, IIEF-5 and IPSS. Data were obtained preoperatively and at 1, 3 and 6 months after surgery. [Results] There was no significant difference in the demographic data among groups. Greater urinary leakage and pelvic floor muscle weakness in the first month compared to pre treatment improved after 3 and 6 months postoperative, without difference among groups. [Conclusion] The muscle strength recovery occurs independently of the therapy employed. Pelvic floor exercises or electrical stimulation also did not have an impact on the recovery of urinary continence and erectile function in our study.

Erectile dysfunction in ankylosing spondylitis patients

Background

Rheumatic diseases such as ankylosing spondylitis (AS) may be associated with sexual dysfunction.

Aim

To study erectile function of a group of Brazilian AS patients comparing them with controls.

Materials and Methods

This was a cross sectional study approved by the local Committee of Ethics in Research. The questionnaire IIEF (International Index of Erectile Function) was applied to 40 AS patients and 40 healthy controls. AS patients had determination of disease activity (through BASDAI or Bath Ankylosing Spondylitis Disease activity index), ASDAS (Ankylosing Spondylitis Disease Activity Score, MASES or Maastricht Ankylosing Spondylitis Score and SPARCC or Spondyloarthritis Research Consortium of Canada), function (through BASFI or Bath Ankylosing Spondylitis Functional Index and HAQ or Health Assessment Questionnaire) and BASMI (Bath Ankylosing Spondylitis Metrological Index).

Results

AS patients had a median score on IIEF of 22.0 (IQR=18-25) while controls had 29 (IQR=27-30) with p<0.0001 Only 17.5% of the AS patients had no erectile dysfunction, in opposite to 87.5% of controls (p<0.0001). IIEF scores had a negative association with BASDAI (p<0.0001), HAQ (p=0.05), body mass index (P=0.03), MASES (P=0.02) and SPARCC (P=0.02) in a univariate analysis. Multiple regression showed that BASDAI was the only variable independently associated with IIEF.

Conclusion

There is a high prevalence of erectile dysfunction among AS patients that is associated with disease activity measured by BASDAI.

Erectile Dysfunction Symptoms in Polydrug Dependents Seeking Treatment

OBJECTIVE

To assess erectile dysfunction (ED) symptom prevalence, sexual behavior conditions, and risk factors associated to ED in a male polydrug dependent sample.

METHODS

A cross-sectional design study was conducted with 102 substance-dependent male polydrug users who sought outpatient treatment in São Paulo, Brazil. Sociodemographic data, drug of choice, chronic disease questions, sexually transmitted infections, International Index of Erectile Function (IIEF) scale, Sexual Addiction Screening Test (SAST), and WHOQOL-Bref instrument were used.

RESULTS

The erectile dysfunction prevalence was 32.3% and it was related to the marital status (single) (p < 0.001), occupational status (fully unemployed) (p < 0.001), presenting a chronic disease (p = 0.027), and with types of sexual partnerships (occasional partner) (p < 0.001). Alcohol (73.5%), tobacco (79.4%), cannabis (83.3%), and cocaine (snorted 78.4% and smoked 42.2%) were the drugs of choice. The ED risk decreased when marital status was married (odds ratio = 3.2 CI95% 1.411-7.518) and with chronic disease (odds ratio 0.06 CI95% 0.00-0.97), while having occasional sexual partners increased 14 times ED risk (OR 14.0 CI95%1.62-122.18). There were no significant associations between quality of life, DOC and ED.

CONCLUSION

Approximately one third of the substance dependents in this sample presented ED. There is a need to integrate psychiatric and clinical care in substance treatment services, and to improve the provision of sexual health care and support available for this population.

Validation of Portuguese version of Quality of Erection Questionnaire (QEQ) and comparison to International Index of Erectile Function (IIEF) and RAND 36-Item Health Survey

PURPOSE

To validate the Quality of Erection Questionnaire (QEQ) considering Brazilian social-cultural aspects.

MATERIALS AND METHODS

To determine equivalence between the Portuguese and the English QEQ versions, the Portuguese version was back-translated by two professors who are native English speakers. After language equivalence had been determined, urologists considered the QEQ Portuguese version suitable. Men with self-reported erectile dysfunction (ED) and infertile men who had a stable sexual relationship for at least 6 months were invited to answer the QEQ, the International Index of Erectile Function (IIEF) and the RAND 36-Item Health Survey (RAND-36). The questionnaires were presented together and answered without help in a private room. Internal consistency (Cronbach's α), test-retest reliability (Spearman), convergent validity (Spearman correlation) coefficients and known-groups validity (the ability of the QEQ Portuguese version to differentiate erectile dysfunction severity groups) were assessed.

RESULTS

We recruited 197 men (167 ED patients and 30 non-ED patients), mean age of 53.3 and median of 55.5 years (23-82 years). The Portuguese version of the QEQ had high internal consistency (Cronbach α=0.93), high stability between test and retest (ICC 0.83, with IC 95%: 0.76-0.88, p<0.001) and Spearman correlation coefficient r=0.82 (p<0.001), which demonstrated the high correlation between the QEQ and IIEF results. The correlations between the QEQ and RAND-36 were significantly low in ED (r=0.20, p=0.01) and non-ED patients (r=0.37, p=0.04).

CONCLUSION

The QEQ Portuguese version presented good psychometric properties and high convergent validity in relation to IIEF. The low correlations between the QEQ and the RAND-36, as well as between the IIEF and the RAND-36 indicated IIEF and QEQ specificity, which may have resulted from the patients' psychological adaptations that minimized the impact of ED on Quality of Life (QoL) and reestablished the well-being feeling.

Erectile dysfunction in methadone maintenance patients: a cross sectional study in northern iran

OBJECTIVE

Erectile dysfunction affects quality of life and is a common dysfunction in drug abusers. The aim of this study was to evaluate the frequency of erectile dysfunction in drug abusers on methadone maintenance therapy to reduce this drug side effect in the future studies.

METHODS

This cross-sectional study was conducted with two hundred addicted individuals on methadone maintenance therapy. Erectile dysfunction was surveyed using the International Index of Erectile Function (IIEF). Finally, all data were collected and analyzed by descriptive statistics such as measures of variability and central tendency and Chi-squared (χ(2)) test using SPSS Version18.0 software.

RESULTS

The amount of the total frequency of erectile dysfunction was pointed 30 or less among the two hundred patients and included the moderate and severe cases. In this study, the number of patients with erectile dysfunction was fifty three (26.5%).

CONCLUSION

The frequency of erectile dysfunction in our study was approximately 1.5 times of prevalence of the public (16.1%). In this study, all the factors related to sexual function such as erectile function, libido, orgasm, and sexual pleasure showed a decline among drug abusers.
