Project description:BackgroundGiven the relevance of social support on the mental health of older adults, having an instrument to evaluate this variable is essential for research in the area. However, mainly, having instruments with suitable evidence of their psychometric properties is critical. For this reason, this study sought to evaluate the factorial and reliability structure of the Multidimensional Scale of Perceived Social Support within autonomous older adults from the Province of Concepción, Chile.MethodsWe surveyed 399 older adults using quote sampling. They answered a Spanish version of the Multidimensional Scale of Perceived Social Support, plus a sociodemographic questionnaire. We performed confirmatory factor analysis using Weighted Least Squares Means and Variances adjusted estimation (WLSMV) to compare the factor models proposes by previous studies. To evaluate reliability, we calculated Cronbach's alpha and McDonald's omega.ResultsThe Confirmatory factor analysis found that the 3-factors models showed the best fist index between the models with CFI = 0.991, TLI = 0.989, and SRMR = 0.035, even though RMSEA were over the cutoff point. The factors presented reliabilities from α = 0.858 to α = 0.941, and from ω = 0.937 to ω = 0.972.ConclusionsThe results support the existence of three factors for the Multidimensional Scale of Perceived Social Support (MSPSS), differentiating the support perceived from Family, Friends, and significant others. All factors present good or excellent reliability. This solution is theoretically consistent and coherent with the literature, and it presents evidence in favor of the use of MSPSS as a measurement to distinguish the support perceived source.

Project description:BackgroundAttitude towards condom use is an important predictor of consistent condom use. However, this topic is an understudied area in Chinese populations, and no validated Chinese instrument is available to capture condom attitude. To fill this research gap, the present study aimed to evaluate the psychometric properties of the University of California, Los Angeles (UCLA) Multidimensional Condom Attitudes Scale (MCAS) and assessed the attitudes towards condom use amongst Chinese adults aged 18-29 years old.MethodsIn this cross-sectional study, a total of 500 people aged 18-29 years old were randomly recruited in Hong Kong. The primary outcome was the attitude towards condom use as measured by the UCLA MCAS. Factor structure, internal construct validity, known-group validity and internal consistency were assessed.ResultsInstead of the five-factor structure designed by the original developers of the MCAS questionnaire, this study proposed a novel six-factor scale: (1) Reliability and Effectiveness, (2) Excitement, (3) Displeasure, (4) Identity Stigma, (5) Embarrassment about Negotiation and (6) Embarrassment about Purchase. The internal construct validity and reliability of the new scale were high. The revised MCAS could differentiate between subgroups, including gender, sexual orientation and sexual experience. In terms of attitudes, over 40% of the participants believed that condoms are not reliable, though the vast majority of the sample did not perceive any stigma related to condom use. In addition, more than half (55.4%) of the respondents felt embarrassed to be seen when buying condoms while a quarter (25.8%) felt uncomfortable buying condoms at all.ConclusionsOverall, the psychometric analysis found that attitude to condom use is culturally specific. The study also highlighted the need for more public health campaigns and interventions to help people cope with the embarrassment of purchasing condoms.

Project description:HIV/AIDS is a public health problem that is transmitted through risky sexual behavior. The literature suggests that the perception of HIV risk is a motivator for the prevention of risky sexual behaviors. There is no culturally adapted scale to assess HIV risk perception in the Hispanic-American population. The aim of this research was to develop a scale to assess HIV risk perception in Hispanic-American young adults. A cross-sectional instrumental design was used, with a sample of students from the Chilean city with the highest HIV rates. Participants (n = 524) were between 18 and 33 years old, of whom 51% were women, 84.4% said they were heterosexual and 43.7% said they had not been tested for HIV/AIDS. The final scale has 9 items and 2 dimensions: (1) perceived risk susceptibility and (2) perceived risk severity. The results showed that the identified structure provided adequate levels of reliability (? > .8) and presented evidence of validity, based on the internal structure of the test (i.e., using ESEM) and on the relationship with other variables (i.e., the sexual risk behaviors scale). In addition, the results showed strong invariance between the scores for men and women. It is concluded that the HIV risk perception scale has adequate psychometric properties to assess HIV risk perception in equivalent samples.

Project description:Background and objectivesScholarly research has established the role of altruism in facilitating human cooperation and prosocial behaviors and highlighted its contribution to psychological well-being. Given the health significance of altruistic attitudes and orientations, we developed a valid and reliable measure of this construct that is suitable for use with older adults.Research design and methodsBased on data from a long-term panel study on adaptation to frailty among older adults (n = 366; mean age = 86 years), we used confirmatory factor analysis to perform construct validation of a five-item Elderly Care Research Center Altruism Scale among older adults (e.g., "Seeing others prosper makes me happy"). Moreover, we examined the invariance of the scale's factor structure across time and gender using nested models.ResultsComposite reliability (coefficient omega = 0.78), factor loadings (>0.45 with eigenvalue = 2.84) from exploratory factor analysis, and model fit indices (e.g., comparative fit index = 0.999) from confirmatory factor analysis suggest a single factor, supporting a unidimensional reliable construct of altruistic orientation at baseline. The results provided support for configural, metric, and scalar invariance across time. Findings pertaining to measurement invariance across gender confirmed full configural invariance but only offered support for partial metric, scalar, and residual invariance at baseline. Strong correlations among the altruism scale, salient personality traits, psychological well-being, religiosity, and meaning in life help establish construct validity.Discussion and implicationsThe availability of a reliable and valid measure of altruistic attitudes enables a comprehensive evaluation of altruism's influence on later-life health and well-being.

Project description:BackgroundInfection by HIV and other STIs and unplanned pregnancies are among the most serious problems associated with sexuality. Male and female condoms are the only dual-purpose devices to control both unplanned pregnancies and STIs, and studying people's attitudes toward the use of these devices are excellent ways to predict their use. Therefore, the purpose of the present study was to adapt and validate the Female Condom Attitude Scale for Spanish language and to evaluate the use of female condoms in Colombian population.MethodsFor that purpose, a total of 387 Colombian women aged 23.68 years in average were asked to respond to the Female Condom Attitude Scale, the Sexual Opinion Survey, and the UCLA Multidimensional Condom Attitudes Scale.ResultsThe use of female condom in Colombia is very low; only 5.10% of the surveyed women had used it at least once. On the other hand, results revealed a five-factor dimensionality (Sexual pleasure enhancement, Inconvenience, Improved prophylaxis, Sexual pleasure inhibition, and Insertion reluctance) with alphas between .81 and .96. The scale also showed adequate psychometric properties and criterion validity. No relationship was found between attitudes toward female condom and attitudes toward male condom.ConclusionsThe Spanish adaptation of the Female Condom Attitude Scale was found to be reliable and valid in a sample of young women.

Project description:AimsTo examine the association between alcohol prices and age of initiation of alcohol use and the association between age of alcohol use initiation and heavy episodic drinking (HED) among adolescents in Chile.DesignWe estimated discrete-time hazard models using retrospective data and generalized ordered probit models with repeated cross-sectional data.SettingChile.ParticipantsA total of 248 336 urban youth who attended secondary school between 2003 and 2015 and self-reported ever having tried alcohol.MeasurementsWe created drinking histories from self-reported responses of age, age of alcohol use initiation and year/month of survey. From two self-reported responses, we created a four-category ordinal variable of heavy episodic drinking: none, one to two, three to nine and more than 10 HED episodes in the past 30 days. We constructed a monthly measure of real alcohol prices using the all-items and alcohol component of the Consumer Price Index compiled by Chile's statistical agency, the Instituto Nacional de Estadísticas.FindingsFirst, we found negative, statistically significant and policy-meaningful associations between alcohol prices and the age of alcohol use initiation. The estimated price elasticity of delay was -0.99 [95% confidence interval (CI) = -1.30, -0.69]. A 10% increase in real alcohol prices was associated with delayed alcohol use initiation of approximately 6.6 months. Secondly, we found that youth who had started drinking alcohol at a later age had statistically significant and substantially lower probabilities of having reported HED during the previous month. For example, youth who started drinking at 16 were 4.9 (95% CI = 4.2-5.6) percentage points more likely to have reported no HED in the previous month relative to youth who started drinking alcohol when aged 12 years or younger.ConclusionsIncreasing the price of alcohol products may delay alcohol initiation among young people in Chile. Chilean youth who start drinking alcohol later may engage in less harmful drinking practices.

Project description:To validate short-form-36 health survey (SF-36) with specific scoring algorithm obtained in a large sample of Chilean older people and to associate quality of life in this sample with social and health related factors. A cross-sectional study on 2,143 community-living subjects aged 60-92 years (33 % men and 67 % women) conducted in Santiago, Chile. Scores in 8 scales of SF-36-physical function (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH)-, were calculated. Factor analysis was used to extract two principal factors and logistic regression model was applied to estimate its association with socio-demographic and health variables. The internal consistency of scales was high (Cronbach's alpha 0.86-0.87). Factor analysis retained two factors: mental (MCS) and physical (PCS) components accounting for 65.3 % of total variance (55.3 and 10.0 % respectively). High correlations (0.61-0.94) between MCS and MH, V, RE and SF were obtained. PCS correlated highest (0.72-0.86) with RP, PF and BP. Self-perceived symptoms of depression (GDS-15 ≥5) was the main variable explaining low scores in both MCS and PCS (adjusted OR = 26.9; 95 % CI: 15.3-47.2; OR = 3.4; 95 % CI: 2.1-5.5, respectively). We have demonstrated the reliability and validity of SF-36 questionnaire to evaluate health related quality of life, reporting Chilean-Specific factor score coefficients for MCS and PCS based in national Chilean means and standard deviations for older people. After adjusting by age and gender, the main predictors of low health related QoL in Chilean older people were self-perceived symptoms of depression, the presence of two or more chronic diseases and illiteracy. Important gender inequalities were observed in all of these results, being consistently less favorable in women than in men.

Project description:BACKGROUND/OBJECTIVE:STIs and HIV/AIDS are an important public health problem, transmitted by risky sex behaviours. In this context, it is necessary to identify protective factors, of those behaviours, as sexual self-concept. Sexual self-concept is a multidimensional trait (i.e. sexual self-esteem; sexual self-efficacy; and sexual assertiveness), but, in an extensive review, we did not find any measure to assess this multidimensional construct in a Spanish-speaking context. The objective of this research is development a scale to assess sexual self-concept in young people and adults. METHOD:Time-space sampling with a total size of 792 participants, coming from the two Chilean cities (i.e. Arica and Iquique) with the highest HIV rates, aged between 17 and 53 years old (ME = 23.42; SD = 6.33), with 66.2% women (N = 500), 33.6% men (N = 258). RESULTS:Final scale has 16 items and 4 dimensions: sexual self-esteem, sexual self-efficacy, assertive sexual communication, and assertive sexual behaviour. The identified structure provides satisfactory levels of reliability (ω > .8) and presents robust evidence of validity, based on the internal structure of the test, using ESEM (RMSEA = .060; CFI = .99; TLI = .98), evidence of validity based on relationship to other variables (i.e. risky sexual behaviour) and measurement invariance between men and women. CONCLUSIONS:The multidimensional scale of sexual self-concept has adequate psychometric properties to assess sexual self-concept in equivalent samples.

Project description:One key strategy to improve treatment access for persons with opioid use disorder (OUD) is overcoming stigma that is internalized by such individuals. Because few theoretically-derived, multidimensional measures of substance abuse stigma exist, we contribute a brief, theoretically-based measure of opioid-related stigma (adapted from Corrigan's Self-Stigma of Mental Illness Scale) to assess perceived stigma and internalized stigma among individuals with OUD. This study presents initial validation of the newly-developed Brief Opioid Stigma Scale among 387 adults who entered an inpatient opioid managed-withdrawal program. The scale assesses: (1) Stereotype awareness ("Aware"), or the extent to which individuals who use opioids perceive community members to believe OUD-related stereotypes; (2) Stereotype agreement ("Agree"), or the endorsement of stigmatizing beliefs by individuals who use opioids; (3) Self-esteem decrement ("Harm"), or the diminution of self-esteem due to these negative stereotypes' impacts on self-worth. Psychosocial measures including self-esteem, depressive symptoms, mental and physical functioning, and desire for aftercare OUD medication treatment, were administered to assess construct validity. Results showed that greater endorsement of the "harm" stigma subscale was associated with greater depressive symptoms, lower self-esteem, and poorer mental and physical functioning. The "aware" stigma subscale displayed similar overall patterns of associations with self-esteem and depression but to a lesser magnitude. The "aware" stigma subscale was positively associated with desire for aftercare methadone and naltrexone treatment, and the "harm" subscale was positively associated with desire for aftercare buprenorphine treatment. Results indicated good initial construct validity. Tailored stigma interventions are recommended for specific aftercare OUD medication treatments.

Project description:ObjectiveWe tested an integrated social-cognitive model derived from multiple theories of the determinants of young people's condom use in Sub-Saharan Africa. The model comprised seven social-cognitive antecedents of condom use: Attitudes, norms, control, risk perceptions, barriers, intentions, and previous condom use.MethodWe conducted a systematic search of studies including effects between at least one model construct and intended or actual condom use in young people from sub-Saharan African countries. Fifty-five studies comprising 72 independent data sets were included and subjected to random-effects meta-analysis. Demographic and methodological variables were coded as moderators. Hypotheses of the integrated model were tested using meta-analytic structural equation modeling.ResultsThe meta-analysis revealed significant nontrivial sample-weighted correlations among most model constructs. Moderator analyses revealed differences in six correlations for studies that included a formative research component relative to studies that did not. There was little evidence of systematic moderation of relations among model constructs by other candidate moderators. Meta-analytic structural equation models revealed significant direct effects of attitudes, norms, and control on condom use intentions, and of intention, control, and barriers on condom use. Including past condom use increased explained variance in condom use intentions and behavior but did not attenuate model effects. There were also significant indirect effects of attitudes, norms, and control on condom use through intentions.ConclusionsFindings provide preliminary evidence to support the integrated condom use model in sub-Saharan African youth. The model provides guidance on potential targets for improving the effectiveness of condom promotion interventions. (PsycINFO Database Record
