This study focused on four aspects of parental monitoring of Internet use by their children: parental supervision, communication
and tracking, and adolescent disclosure. Data were obtained from a SAFT (Safety Awareness for Teens Project) national survey
of Singapore youths and parents regarding Internet safety at home. Study 1 examined 1,124 adolescents and 1,002 parents; Study
2 examined a subsample of 169 dyads of adolescents and their parents. Frequency of use and engagement in risky Internet behaviors
such as visiting inappropriate websites were analysed. The results indicated that parents tend to underestimate adolescents’
engagement in risky Internet behaviors and overestimate the amount of parental monitoring regarding Internet safety that occurs
at home. The study suggested that mothers have a better awareness of their adolescents’ Internet use than fathers. The findings
were explained in the context of parental monitoring. The results suggest that parental monitoring needs to be reconceptualized
and that parents need to improve the communication with their adolescents regarding Internet use. 相似文献

Dimensionality of the widely used Rosenberg’s Self-Esteem Scale (RSES) was investigated in a sample of 153 seventh-grade Asian
students from Singapore. Confirmatory factor analyses performed on the scores of the RSES revealed two factors (positive and
negative self-esteem) as hypothesized. Both factors were empirically related to different external variables. Results from
multiple regression analyses indicated that positive self-esteem significantly predicted students’ mastery goal orientation
and academic self-efficacy scores while negative self-esteem significantly predicted students’ disruptive behavior. These
findings provide some preliminary support that the two factors could possibly be measuring substantively distinct dimensions,
thus calling into question the unidimensionalty of the RSES in an Asian school-based sample.

This report examined whether Virtual Reality Exposure Therapy (VRET) could be used in the treatment of posttraumatic stress disorder (PTSD) symptoms in the aftermath of a serious motor vehicle accident. Six individuals reporting either full or severe subsyndromal PTSD completed 10 sessions of VRET, which was conducted using software designed to create real-time driving scenarios. Results indicated significant reductions in posttrauma symptoms involving reexperiencing, avoidance, and emotional numbing, with effect sizes ranging from d=.79 to d=1.49. Indices of clinically significant and reliable change suggested that the magnitude of these changes was meaningful. Additionally, high levels of perceived reality ("presence") within the virtual driving situation were reported, and patients reported satisfaction with treatment. Results are discussed in light of the possibility for VRET to be useful in guiding exposure in the treatment of PTSD following road accidents. 相似文献

ABSTRACT In light of the lack of studies examining the cognitive components of affective chronometry, this research examined the appraisals associated with emotion habituation, using anger as the emotion of focus. Anger and its appraisals were assessed repeatedly over a day in the participants' naturalistic contexts. The trajectory of decline in anger over time after its first appearance was found to be a function of chronic coping styles. More importantly, the trajectories of anger-related appraisals generally corresponded to that of anger and were also moderated by coping styles in ways consistent with the moderating effects of coping styles on anger. Implications of these results for affective chronometry research and for appraisal research are discussed. 相似文献

The choice of a major by a college student is viewed as depending upon the quantity of various outputs (such as income and status) each major provides and the taste structure of the student for these outputs. Tradeoffs in outputs occur so that high status may overcome low-income potential in the occupation into which the major provides entry. Different taste structures among students mean tradeoffs occur at different rates, so that taste structues are best associated with student major selection in a probability sense. Changes in the probability of selecting a collegiate major are associated with changes in student taste structures via a conditional logit model. The taste structure of a student is hypothesized to depend upon the environment in which the student was raised and the environment in which the student now lives. The relationship between environment and taste is also best stated in a probability sense and a second logit model is used to describe this relationship. Estimation of the two logit models, using survey data, attempts to quantify the hypothesized route from environment to taste structure to major selection for entry into an occupation. An example of this route is the finding that women students place more importance on obtaining high income than do men students and the greater the importance of high income, the lower the probability of selecting an education major, the greater the probability of selecting a humanities or social science major. Other results of estimation are presented and discussed. 相似文献

Excitation of the mesocorticolimbic pathway, originating from dopaminergic neurons in the ventral tegmental area (VTA), may be important for the development of exaggerated fear responding. Among the forebrain regions innervated by this pathway, the amygdala is an essential component of the neural circuitry of conditioned fear. The functional role of the dopaminergic pathway connecting the VTA to the basolateral amygdala (BLA) in fear and anxiety has received little attention. In vivo microdialysis was performed to measure dopamine levels in the BLA of Wistar rats that received the dopamine D(2) agonist quinpirole (1 μg/0.2 μl) into the VTA and were subjected to a fear conditioning test using a light as the conditioned stimulus (CS). The effects of intra-BLA injections of the D(1) antagonist SCH 23390 (1 and 2 μg/0.2 μl) and D(2) antagonist sulpiride (1 and 2 μg/0.2 μl) on fear-potentiated startle (FPS) to a light-CS were also assessed. Locomotor performance was evaluated by use of open-field and rotarod tests. Freezing and increased dopamine levels in the BLA in response to the CS were both inhibited by intra-VTA quinpirole. Whereas intra-BLA SCH 23390 did not affect FPS, intra-BLA sulpiride (2 μg) inhibited FPS. Sulpiride's ability to decrease FPS cannot be attributed to nonspecific effects because this drug did not affect motor performance. These findings indicate that the dopamine D(2) receptor pathway connecting the ventral tegmental area and the basolateral amygdala modulates fear and anxiety and may be a novel pharmacological target for the treatment of anxiety. 相似文献

This study compared retrospective reports of childhood sexual and physical abuse as assessed by two measures: the Childhood Trauma Questionnaire (CTQ), which uses a Likert-type scaling approach, and the Computer Assisted Maltreatment Inventory (CAMI), which employs a behaviorally specific means of assessment. Participants included 1,195 undergraduate students recruited from three geographically diverse universities. Agreement was high across the two measures in the classification of victim status (92% and 80% for sexual and physical abuse, respectively). However, the CTQ classified more participants as sexually abused than did the CAMI, whereas the opposite trend was found for physical abuse. For child physical abuse, many participants reporting abusive acts on the CAMI scored below the cut-point for physical abuse on the CTQ. Classification differences for both types of abuse were largely unrelated to demographic factors, socially desirable responding, or self-reported withholding of information. The implications of these results are discussed in light of future research using retrospective methods of assessing childhood abuse. 相似文献

The influence of a family history of suicide on suicide attempt rate and characteristics in depression, schizophrenia, and opioid dependence was examined. One hundred sixty inpatients with unipolar depression, 160 inpatients with schizophrenia, and 160 opioid-dependent patients were interviewed. Overall, a family history of suicide was associated with a higher risk for suicide attempt, with high-lethality method, with repeated attempts, and with number of attempts, while the interaction between family history and diagnostic group was not significant. Thus, a positive family history of suicide was a risk factor for several suicide attempt characteristics independent of psychiatric diagnosis. 相似文献
