Identifying the factors associated with mental health services use (MHSU) is an important step in developing strategies to improve services access and delivery. The aims of the present study were to (a) identify personality and individual difference characteristics associated with MHSU intentions within the framework of the Theory of Planned Behavior (TPB) and (b) explore complex relationships that might exist between these characteristics and determinants of MHSU intentions identified in TPB, including attitudes, subjective norms, and perceived behavioral control. Data for 244 Canadian Armed Forces recruits who completed a MHSU questionnaire following mental health training were linked to personality data collected earlier. Multivariate analyses showed that the relationship between agreeableness and MHSU intentions was mediated by instrumental attitudes and subjective norms. The relationship between hardiness and MHSU intentions was mediated by subjective norms and self-efficacy. Findings suggest it may be worthwhile to consider mental health education initiatives to improve MHSU.  相似文献

We investigated the social image of anabolic steroids (AS) users grounding our analysis on the achievement goal theory of Nicholls. Our main goal was to explore how an athlete’s acceptance of AS use would impact on the way that athlete will be perceived by others. Non‐AS‐using participants reacted to one of two scenarios portraying a male athlete either accepting or refusing to engage in drug use behavior. The results suggested that the acceptance of anabolic steroids yielded an unfavorable social image – perceivers inferred a predominant ego orientation to characterize the AS‐user’s motivation as well as weaker sportspersonship and a stronger proclivity for reactive aggression than instrumental aggression. Moreover, the analyses did not yield significant gender or interaction effects. Finally, those findings are commented in view of methodological shortcomings and of the perspectives that they may offer for future research concerning the motivational aspects of the social perceptions of drug use in sport.  相似文献

From September 2007 to May 2011 a total of 471 participants (325 males and 146 females) signed up for an 8‐week Internet‐based cognitive behavioral therapy offered for gamblers in Finland. Sixty‐four percent of the participants were pathological gamblers (PGs) (NODS 5> points), 14% were problem gamblers (NODS 3–4 points) and 10% were at risk of gambling problems (NODS 1–2 points). Two hundred and twenty four participants completed the treatment and after the treatment period significant changes were found in the following variables: gambling related problems (NODS), gambling urge, impaired control of gambling, alcohol consumption (AUDIT‐C), social consequences, gambling‐related cognitive erroneous thoughts and depression (MARD‐S). In this sample co‐morbid alcohol consumption was stronger among males. The main finding of this study was that the onset age of gambling was associated with a greater amount of gambling‐related cognitive erroneous thoughts.  相似文献

Functional tool usage is a critical aspect of our daily lives. Not only must we know which tools to use for a specific action goal, we must also know how to manipulate those tools in meaningful way to achieve the goal of the action. The purpose of this study was to identify the regions of the brain critical to supporting the process of understanding errors in tool manipulation. Using fMRI, neural activations were recorded while subjects were presented with images demonstrating typical action scenes (screwdriver used on a screw), but with the tool being manipulated either correctly (screwdriver held by handle) or incorrectly (screwdriver held by bit rather than handle). Activations in fMRI for identifying correct over incorrect tool manipulation were seen along the canonical parietofrontal action network, while activations for identifying incorrect over correct tool manipulation were primarily seen at superior temporal areas and insula. We expand our hypotheses about ventral brain networks identifying contextual error to further suggest mechanisms for understanding functional tool actions, which collectively we regard as functional affordances. This proposes a fundamental role for ventral brain areas in functional action understanding.  相似文献

Objective : Because interpersonal discussion about condom use can encourage subsequent condom use, this project aims to examine the psychological antecedents of intentions to discuss or request the use of condoms with a sexual partner.

Method : The data were collected from 849 heterosexual college students in the USA through an online survey. The survey contained several measures related to attitude functions (i.e. motivations), efficacy, norms and intentions to discuss condom use with a sexual partner.

Results : Participants’ attitude functions weakly predicted intentions to discuss condom use. Communication efficacy was a more important predictor of intentions for females (vs. males) and for those in other relationships or not in a relationship (vs. long-term monogamous relationships). Anticipated negative emotions were a stronger predictor of intentions for those in long-term monogamous relationships (vs. other relationships or not in a relationship).

Implications : Future research needs to consider more detailed attitude functions and anticipated emotions. Furthermore, background variables (e.g. gender and relationship status) can be moderators in addition to being distal predictors.  相似文献

Based on the Theory of Planned Behaviour (TPB), the purpose of this investigation was to examine the directionality of the association among condom use, intention, attitudes, subjective norms and perceived behavioural control. The present study investigated the nature of these relationships using a longitudinal cross-lagged design applied to data from a cohort of 958 randomly selected Italian adults. Using structural equation modelling, two cross-lagged panel analyses revealed reciprocal relationships between intention and attitudes and between intention and condom use. Contrary to expectations, baseline subjective norms and perceived behavioural control did not predict subsequent intention to use condom when controlled for the autoregressive effect of intention at T1 on the same variable at T2. Also, perceived behavioural control at T1 did not influence condom use at T2 after controlling for the effect of baseline intention. The possibility of reciprocity was also tested for all relations and significant results were found. The moderation effect of perceived behavioural control on the relationship between intention and condom use was not significant. The differences in age, gender and partnership status were taken into account in the analyses.  相似文献

Abstract

Screening for head and neck cancer is underutilized. Given that lack of knowledge of the risk factors may partially account for screening underutilization. we surveyed subjective risk and knowledge of risk factors for head and neck cancer among 124 individuals who attended a free. hospital-based head and neck cancer screening. Few participants were current smokers. Most attendees perceived their risk as similar to others of their age and sex. Personal health habits comprised almost all of the risk-decreasing factors, yet less than half of the risk-increasing factors. generated. Personal habits were less frequently endorsed than factors such as pollution and heredity. Those who mentioned a risk behavior, or a family cancer history, reported higher subjective risk. Those who mentioned a personal health habit reported lower subjective risk. Results highlight needed efforts to increase screening among high-risk individuals through targeted education messages.  相似文献

Abstract

The present study was designed to examine the effect of information about the high prevalence of safe sex on condom use intention, and to investigate the possible mediating role of the perceived social norm of friends, and the perceived social norm of future. sexual partners. Participants were provided with gender specific prevalence information, that is with the information that most men have exclusively safe sex, or with the information that most women exclusively engage in safe sexual behavior. The results show some gender differences. Information about the high prevalence of safe sex among men tends to increase women's condom use intention, and this effect seems to be mediated by the paceived social norm of future sexual partners. Men's intention, on the other hand, seems to be unaffected by high prevalence information of safe sex. Implications for research and prevention are discussed  相似文献

Despite a paucity of studies evaluating the psychometric properties of the Locus of Control of Behaviour Scale (LCBS), it continues to be widely used in behavioural research. The present study sought to redress this gap in the literature. The 17‐item LCBS was administered to 373 Australians attending Alcohol and Other Drug (AOD) treatment agencies in the northern metropolitan region of Perth. Confirmatory factor analyses were conducted in order to determine which of several plausible measurement models provided the best fit for the data. A unidimensional model, recommended by the authors of the LCBS, and a two‐dimensional (Internal Locus of Control vs External Locus of Control) model provided poor fits. Other multidimensional models, differing only in the dimensionality of the externality factor, were also tested. A multidimensional model consisting of an Internal Locus of Control factor and four component External Locus of Control factors provided the best fit; however, the fit is probably best described as “reasonable” rather than “good.” A subsequent exploratory factor analysis using parallel analysis indicated a cohesive internality factor; however, the externality factor showed a tendency to fragment into smaller components. Results were discussed in terms of the problematic externality factor.  相似文献
