There has been a growing interest in using the Internet to access a variety of populations for prevention education and health care. It is not clear that this is viable for homeless and other marginalized populations. The purpose of this study was to describe Internet access and use among a sample of homeless and indigent drug users. A brief questionnaire was developed to assess computer ownership, use, email, and Internet access and use. Participants were recruited through a community-based human immunodeficiency virus (HIV) prevention program. 265 participants completed the questionnaire. While 55% had ever used a computer in their lifetime, only 25% had ever owned a computer, 24% had ever had their own email account, 33% had access to a working computer in the last 30 days, 10% had sent or received email in the last 30 days, and 19% had surfed or accessed information on the Internet in the last 30 days. Logistic regression predicting lifetime use of a computer showed predictive factors of having completed high school (Odds Ratio [OR] = 4.5; 95% Confidence Interval [CI] = 2.41, 8.38) and number of days used amphetamines in the last 30 days, per 5 days of use (OR = 1.64; 95% CI = 1.18, 2.27). Inversely related were age, per 5 years of age (OR = 0.78; 95% CI = 0.65, 0.93) and number of days used marijuana in the last 30 days, per 5 days of use (OR = 0.97; 95% CI = 0.76, 0.99). Very low access and usage suggest that Internet-based public health education models be reexamined for this population. The association with amphetamine use may indicate a facilitating effect of amphetamine by heightening awareness and increasing wakefulness.  相似文献

This investigation tested whether social norms and endorsement of humanitarian values interact to influence authoritarians' attitudes toward immigrants. Oyamot, Borgida, and Fisher (2006) found correlational evidence for a model in which: (1) clear social norms for attitudes toward an outgroup (favorable or unfavorable) influence the authoritarianism–attitude relationship in the direction of the norm, and (2) in the absence of clear social norms, endorsement of humanitarian–egalitarian values attenuate the intolerant tendencies of authoritarians. The current investigation tested the model in a survey experiment conducted in a diverse adult sample (N = 388). We measured participants' levels of authoritarian predisposition and endorsement of humanitarian values. Participants were then randomly told that Americans in general had either negative, positive, or mixed opinions about immigrants and immigration (social norm condition), and then asked about their attitude toward immigrants. Consistent with the model, authoritarianism was negatively related to attitudes toward immigrants in the negative norm condition. However, authoritarians' tendency toward intolerance was attenuated when they thought that Americans in general had positive opinions about immigrants. Also as predicted, when societal norms were depicted as mixed, authoritarians' attitudes depended upon endorsement of humanitarian values: humanitarian authoritarians held positive attitudes and non-humanitarian authoritarians held the most negative attitudes toward immigrants. Implications for understanding the effects of authoritarian predispositions in varying social contexts are discussed.  相似文献

State mood has been proposed as a facilitator of creative behavior. Whereas positive mood compared to neutral mood generally facilitates creative performance, mood effects are weaker and less consistent when positive mood is compared to negative mood. These inconsistent results may be due to focusing only on mood valence, while neglecting or confounding mood activation. The current study is based on the dual-pathway model, which describes separate roles for mood valence and mood activation in facilitating creativity. We used experience sampling methodology to investigate the concurrent and lagged effects of mood valence and activation on creative process engagement (CPE) within-person over time among individuals working on a long-term project requiring creativity. We also investigated the moderating effects of individual differences in goal orientation and supervisory support on within-person mood-creativity relationships. As expected, we found that activating positive and activating negative moods were positively associated with concurrent CPE, whereas deactivating moods of both valences were negatively related to CPE. Activating negative mood had a significant lagged effect on CPE, whereas activating positive mood did not. We also found that activating positive mood was more strongly related to concurrent CPE among individuals with high rather than low learning goal orientation. Further, activating positive mood interacted with prove goal orientation and supervisory support for creativity, such that activating positive mood had the strongest association with CPE when both prove goal orientation and supervisory support were high.  相似文献

Aggression between partners represents a potential guiding force in family dynamics. However, research examining the influence of partner aggression (physically and psychologically aggressive acts by both partners) on harsh parenting and young child adjustment has been limited by a frequent focus on low-risk samples and by the examination of partner aggression at a single time point. Especially in the context of multiple risk factors and around transitions such as childbirth, partner aggression might be better understood as a dynamic process. In the present study, longitudinal trajectories of partner aggression from birth to age 3 years in a large, high-risk, and ethnically diverse sample (N = 461) were examined. Specific risk factors were tested as predictors of aggression over time, and the longitudinal effects of partner aggression on maternal harsh parenting and child maladjustment were examined. Partner aggression decreased over time, with higher maternal depression and lower maternal age predicting greater decreases in partner aggression. While taking into account contextual and psychosocial risk factors, higher partner aggression measured at birth and a smaller decrease over time independently predicted higher levels of maternal harsh parenting at age 3 years. Initial level of partner aggression and change over time predicted child maladjustment indirectly (via maternal harsh parenting). The implications of understanding change in partner aggression over time as a path to harsh parenting and young children's maladjustment in the context of multiple risk factors are discussed.  相似文献

In none of the deception studies that used drawings to date, was the effect of sketching on both speech content and drawing content examined, making it unclear what the full potential is of the use of drawings as a lie detection tool. A total of 122 truth tellers and liars took part in the study who did or did not sketch while narrating their allegedly experienced event. We formulated hypotheses about the total amount of information and number of complications reported and about various features of the drawings. Participants in the Sketch-present condition provided more information than participants in the Sketch-absent condition, and truth tellers reported more details than liars, but only in the Sketch-present condition. In contrast to previous research, no Veracity differences occurred regarding the content of the drawings, perhaps because sketching was introduced as a tool that facilitated verbal recall and not as a stand-alone tool.  相似文献

Idiographic network models based on time‐series data have received recent attention for their ability to model relationships among symptoms and behaviours as they unfold in time within a single individual (cf. Epskamp, Borsboom, & Fried, 2018; Fisher, Medaglia, & Jeronimus, 2018). Rather than examine the correlational relationships between variables in a sample of individuals, an idiographic network examines correlations within a single person, averaged over many time points. Because the approach averages over time, the data must be stationary (i.e. relatively consistent over time). If individuals experience varying states over time—different mixtures of symptoms and behaviours in one moment or another—then averaging over categorically different moments may undermine model accuracy. Fisher and Bosley (2019) address these concerns via the application of Gaussian finite mixture modelling to identify latent classes of time points in intraindividual time‐series data from a sample of adults with major depressive disorder and/or generalised anxiety disorder (n = 45). The present paper outlines an extension of this work, wherein network analysis is used to model within‐class covariation of symptoms. To illustrate this approach, network models were constructed for each intraindividual class identified by Fisher and Bosley (137 networks across the 45 participants, mean classes/person = ~3, range = 2–4 classes/person). We examine the relative consistency in symptom organisation between each individual's multiple mood state networks and assess emergent group‐level patterns. We highlight opportunities for enhanced treatment personalisation and review nomothetic patterns relevant to transdiagnostic conceptualisations of psychopathology. We address opportunities for integrating this approach into clinical practice and outline potential shortcomings.  相似文献

Functional communication training has been reported to be a promising treatment for severe behavior problems. In this study, functional communication training alone and combined with extinction and/or punishment was evaluated for 4 clients with severe retardation, behavior problems, and communication deficits. The participants were inpatients on a hospital unit for treatment of severe behavior disorders. They received individualized interventions based on functional assessment that included reinforcement of a communication response with the same function as their destructive behavior. Results showed that for some patients, functional communication training was not sufficient to produce clinically significant reductions in destructive behavior, and the combination of training plus punishment produced the largest and most consistent reductions.  相似文献

As social media becomes increasingly popular, human subjects researchers are able to use these platforms to locate, track, and communicate with study participants, thereby increasing participant retention and the generalizability and validity of research. The use of social media; however, raises novel ethical and regulatory issues that have received limited attention in the literature and federal regulations. We review research ethics and regulations and outline the implications for maintaining participant privacy, respecting participant autonomy, and promoting researcher transparency when using social media to locate and track participants. We offer a rubric that can be used in future studies to determine ethical and regulation-consistent use of social media platforms and illustrate the rubric using our study team’s experience with Facebook. We also offer recommendations for both researchers and institutional review boards that emphasize the importance of well-described procedures for social media use as part of informed consent.  相似文献
