A group of 100 adults with chronic low back pain (CLBP), drawn from a larger national sample, completed a questionnaire battery
that assessed (among other things) goal conflict and goal self-efficacy, pain severity, pain-induced fear, and 3 months later,
two important clinical outcomes: physical disability and depression. Consistent with emerging motivation-centered models of
adaptation (e.g., Ford, Humans as self-constructing living systems: A developmental perspective on behavior and personality. Erlbaum, 1987; Karoly Review of General Psychology, 3, 264–291, 1999) and cognitive-behavioral accounts of pain-specific fears (e.g., Asmundson et al. Clinical Psychology Review, 19, 97–119, 1999), structural equation analyses revealed that (a) goal self-efficacy, goal conflict, and pain severity independently
predicted pain-induced fear, (b) pain-induced fear fully mediated the effects of goal conflict and goal self-efficacy on physical
disability and depression, and (c) pain-induced fear partially mediated the effects of severity on disability and depression.
Results suggest that clinical pain specialists should treat pain-induced fear as a means of forestalling disability and depression,
and that they should also seek to modify how CLBP patients think about and organize their life goals.

AIM OF THE STUDY: A massive cardiopulmonary resuscitation (CPR) training programme is continued in most hospitals to make hospital personnel ready to take action in cases of cardiac arrest. Motivated course participants learn more and perform better than unmotivated course participants. This study investigates whether hospital personnel are motivated to participate in CPR courses and whether motivation correlates with important assumptions in adult learning. MATERIALS AND METHODS: A survey measuring learning motivation via the MSLQ instrument was performed among 361 hospital personnel before attending a CPR course. Assumptions of adult learning were identified and data were analysed in relation to these assumptions. RESULTS: Hospital personnel are generally motivated for learning CPR. Respondents who had been prepared for the course, who had participated in the decision about attending the course, who were working in high-risk area for cardiac arrest or were nursing personnel working in long-time close contact with patients were more motivated to CPR training than other hospital personnel. It seems like motivation correlates with adult learning assumptions such as the learners need to know, the learners self-concept, readiness to learn and orientation to learning. CONCLUSION: This study supports the assumption that CPR training should be based on an adult learning model. As preparedness, participation, readiness and relevance seem to be key factors, we may want to include these factors when training hospital personnel in CPR skills. 相似文献

OBJECTIVE: Determine whether a six-step behavioral cognitive method is more effective than traditional oral hygiene instruction. METHODS: Thirty-eight patients with chronic periodontitis were randomly assigned to two groups. The control group was given traditional oral hygiene instruction for 20 min. The intervention group received counseling by Farquhar's six-step method for 10 min after traditional oral hygiene instruction. In both groups, oral hygiene instruction was given once a week, and performed three times in total for 3 weeks. Clinical characteristics, deposition of dental plaque, frequency and duration of brushing, frequency of interdental cleaning and scores based on scale of "self-efficacy for brushing of the teeth" were compared in both groups. RESULTS: There were no differences between the two groups in clinical, demographic, behavioral and self-efficacy characteristics at the baseline examination. However after the third visit, the intervention group had a significantly higher self-efficacy, lower plaque index, longer brushing duration and higher frequency of inter-dental cleaning than those of the control group. Multiple regression analysis showed significant association of toothbrushing duration with self-efficacy for brushing of the teeth (p<0.001). CONCLUSION: The six-step method might be more effective for enhancing self-efficacy and behavioral change of oral hygiene than traditional oral hygiene instruction alone. PRACTICE IMPLICATIONS: Dentists and dental hygienists can use the six-step method for effective oral hygiene instruction. 相似文献

BackgroundNegative silence in the classroom is a usual passive behavior, which means students tend to keep silent and are unwilling to participate in the teaching interaction. It hinders the classroom teaching quality severely. Previous studies have shown both self-efficacy and fear of negative evaluation are related to silent behavior. However, little research has explained whether self-efficacy affects negative silence in the classroom through fear of negative evaluation.PurposeTo investigate the relationships between self-efficacy, fear of negative evaluation and negative silence in the classroom.MethodsA cross-sectional survey using convenience sampling was conducted to collect data from 568 undergraduate nursing students from a higher medical institution in Guizhou Province, west of China, from October to November 2021. the T-Test or analysis of variance was used as a univariate analysis and the Bootstrap test was applied to verify the mediating effect.FindingsNursing students' self-efficacy was negatively related to both fear of negative evaluation and negative silence in the classroom(r = −0. 188, P<0. 05; r = −0. 298, P<0. 05, respectively; fear of negative evaluation was positively related to negative classroom silence(r = 0. 392, P<0. 05; mediation analysis showed the mediating effect of fear of negative evaluation accounted for 23. 53% of the total [Effect Value= −0. 08, 95%CI(− 0. 12,− 0. 03].DiscussionFear of negative evaluation partially mediates the relationship between self-efficacy and negative silence in the classroom. Therefore, reducing nursing students' negative evaluation fear can be used as a target for interventions to address nursing students' negative classroom silence issue, promoting the quality of classroom teaching and learning. 相似文献

IntroductionPrior studies show that many patients with diabetes whose health maybe impacted by fasting, choose to fast during Ramadan. This study describes the implementation and evaluation of an online module targeting bachelor of pharmacy (BPharm) and doctor of pharmacy (PharmD) students that aims to improve participants' knowledge, communication, and self-efficacy concerning proper care for patients with diabetes in Ramadan.MethodsAn online module consisting of two phases targeting both BPharm and PharmD students was implemented over two semesters in fall 2020 and spring 2021. Participants were directed to fill pre-module and post-module assessments to evaluate the change in their knowledge and self-efficacy using two scales. Pre- and post-survey data for participants’ knowledge and self-efficacy were analyzed for significance using paired sample t-tests. Qualitative data analysis was performed to assess participants’ responses to the open-ended question concerning what they liked and disliked about the module.ResultsAll BPharm and PharmD students taking the lesson responded to both the baseline survey and the follow-up one resulting in 92 responses (participation rate of 100%). The average score for participants in the pre-module self-efficacy section was 1.5 (SD = 1) and increased post-module to 3.5 (SD = 0.7), t (91) = 20.2, p < 0.001. Further, the average score for participants in the pre-module knowledge section was 14 (SD = 3), which similarly increased to 22 (SD = 3) post-module t (91) = 19.7, p < 0.001. Qualitative analysis provided insights on how participants perceived the module design, content, and its impact on practice. Participants described the module as an informative one that addresses a much-needed issue they haven’t been exposed to before. They emphasized how the module addresses the cultural needs of patients in their communities. They particularly appreciated seeing instructor videos depicting real-life scenarios and the focus on their communication skills, but some preferred learning about this topic through live sessions.ConclusionAn online module positively impacted both self-efficacy and knowledge in relation to caring for patients with diabetes considering fasting in Ramadan. Future studies should explore how different versions of this module can be integrated into educational activities for pharmacy students, pharmacists in different settings, and for other health care professionals. 相似文献

Hair cortisol concentrations (HCC) are assumed to reflect integrated cortisol secretion over extended periods of time and may provide a sensitive marker for stress-associated endocrine changes. Here, we report data from two independent studies of 155 (study I) and 58 participants (study II) in which HCC associations with different stress-related measures and body mass index (BMI) were investigated. Consistent evidence for positive associations between HCC and BMI was seen across both studies (study I: r=.33, p<.001; study II: r=.42, p=.001). On the other hand, findings failed to reveal reliable HCC associations with psychosocial variables, showing only a positive relationship with self-reported social overload in study II (r=.29, p=.03) but not with other stress-related measures. 相似文献
