Work-based learning: Development and validation of a scale measuring the learning potential of the workplace (LPW)

The current study presents a multi-dimensional scale measuring the learning potential of the workplace (LPW), which is applicable across various occupational settings. Based on a comprehensive literature review, we establish four theoretically relevant dimensions of work-based learning, which together constitute the learning potential of the workplace. The psychometric characteristics of our instrument were examined among a sample of Dutch employees working in different organizations (N = 1013). In this study, we tested the factorial structure and validity of the LPW-scale by conducting Confirmatory Factor Analyses, testing for measurement invariance and determining the scale's reliability. Subsequently, the LPW-instrument was cross-validated using SEM (AMOS 20.0). Furthermore, convergent, divergent, and construct validity were investigated. The results empirically supported the theory based four-factor structure of the LPW-scale and provided solid evidence for the sound psychometric properties of the study's instrument.     

I am so Happy ’Cause Today I Found My Friend: Friendship and Personality as Predictors of Happiness

Relying on the theoretical model of [Lyubomirsky et al. 2005, Review of General Psychology, 9, pp. 111–131], the present study investigated the relationship between personality, number of friends, best friendship quality and happiness among 423 young adults (n = 300 women). The main interest was to examine whether friendship contributed to happiness while controlling for personality. Friendship variables accounted for 58% of the variance in happiness. Results revealed that friendship quality predicted happiness above and beyond the influence of personality and number of friends, but friendship conflict was not a significant predictor. Additional analyses revealed that the companionship and self-validation features of friendship quality were predictive of happiness while controlling for gender and personality. The findings were discussed in the light of theory and empirical research and suggestions were made for future research. An erratum to this article can be found at     

Standardized classroom management program: Social validation and replication studies in Utah and Oregon

A comprehensive validation study was conducted of the Program for Academic Survival Skills (PASS), a consultant-based, teacher-mediated program for student classroom behavior. The study addressed questions related to: (a) brief consultant training, (b) subsequent teacher training by consultants using PASS manuals, (c) contrasts between PASS experimental teachers and students and equivalent controls on measures of teacher management skills, student classroom behavior, teacher ratings of student problem behaviors, and academic achievement, (d) reported satisfaction of participants, and (e) replication of effects across two separate school sites. Results indicated that in both sites significant effects were noted in favor of the PASS experimental group for (a) teacher approval, (b) student appropriate classroom behavior, and (c) four categories of student inappropriate behavior. Program satisfaction ratings of students, teachers, and consultants were uniformly positive, and continued use of the program was reported a year later. Discussion focused upon issues of cost-effectiveness, differential site effects, and the relationship between appropriate classroom behavior and academic achievement.     

中医隐性知识结构维度模型的验证性研究

隐性知识大量存在于中医医者知识体系中。深入探讨中医医者隐性知识的结构维度,有利于中医的传承及个体隐性知识的转移。通过文献分析和专家访谈,发现中医隐性知识可以分为学习策略维度、临床技能维度、人际互动维度、情绪情感维度、价值取向维度和中医药文化维度。结合各维度之间的相互关系,构建了中医隐性知识的结构模型。为了提升该维度结构模型的科学性,对国家级名老中医、国医大师、中医院管理者进行了深度访谈和问卷调查,进行了验证性研究。     

DEFINING,VALIDATING, AND INCREASING INDICES OF HAPPINESS AMONG PEOPLE WITH PROFOUND MULTIPLE DISABILITIES

In this study we attempted to operationalize, measure, and increase happiness among people with profound disabilities. Happiness indices were defined and observed among 5 individuals. Validation measures indicated that (a) increases in happiness indices were observed when individuals were presented with most preferred stimuli relative to least preferred stimuli, (b) increases in unhappiness indices were observed when they were presented with least preferred relative to most preferred stimuli, and (c) practitioner ratings of participant happiness coincided with observed indices. Subsequently, classroom staff increased happiness indices through presentation and contingent withdrawal of activities. Results suggested that a behavioral approach can enhance happiness as one aspect of quality of life among people with profound disabilities. Research directions are offered that focus on using a behavioral approach to investigate other private events that are important among people with disabilities.     

Factors affecting the social validity of a role-play test of children's social skills

The social validity of a role-play test of children's social skills, the Social Skills Test for Children (SST-C), was evaluated by 63 subjects (33 adults and 30 children) who subjectively judged the quality of three children's role-play performances. The three children were selected as having high, medium, or low social skill based upon their performance on the SST-C. Assessment of the effects of subject characteristics upon judgments of social skill suggested that similarities in age and race between the subjects and the three children tended to diminish perceived differences in social skill among the three children. It was concluded that the social validity of the role-play test was supported only if the persons evaluating social behavior were dissimilar in age and racial characteristics from the persons who were being evaluated.     

Training public-speaking behavior: an experimental analysis and social validation

The effect of an instructional package on public-speaking behaviors was analyzed in two experiments. The instructional package was designed to teach public-speaking trainees to look at the audience, make gestures, and perform a number of speaking behaviors. The results of Experiment I, with a university student serving as the trainee, showed that the percentage of each category of public-speaking target behavior increased only after the instructional package was introduced for that category. The results of Experiment 2, with three low-income paraprofessional staff members of a neighborhood service center serving as trainees, showed that the percentage of target behaviors increased after the instructional package was introduced for the respective trainee. Audience ratings of public-speaking performance were correlated with direct observations of target responses. All trainees showed marked improvements in audience ratings from pretraining to posttraining. This study demonstrated an effective procedure for training public-speaking behaviors.     

TRAINING COUNSELING SKILLS: AN EXPERIMENTAL ANALYSIS AND SOCIAL VALIDATION

A community development perspective suggests the value of using local resources to solve local problems. Two low-income staff of a community service center served as nonprofessional counselors after receiving a training program consisting of written instructions, practice, and performance feedback. The effects of the 40-hour training program were positive for both counseling and problem-solving skills. There was also evidence of generalization of counseling performance across clients, problems, and time. In addition, expert judges' ratings of performance were obtained as a measure of social validity. These findings suggest that the training procedures are effective in enhancing the counseling and problem-solving skills of low-income nonprofessionals.     

DEVELOPMENT AND EVALUATION OF AN INFANT-CARE TRAINING PROGRAM WITH FIRST-TIME FATHERS

We evaluated the effectiveness of a multicomponent package in training infant-care skills to first-time fathers. After developing and socially validating a set of infant-care skills, we assessed the effects of training in a hospital-based program with expectant fathers (Experiment 1) and in a home-based program with fathers having varied degrees of experience with their infants (Experiment 2). In both experiments, a multiple probe design demonstrated that the training package was responsible for producing criterion performance by the expectant and first-time fathers. A 1-month generalization probe in Experiment 1 showed that the effects transferred across training conditions (training doll to human infant) and settings (hospital to home). An increase in the number of infant-stimulation activities performed by fathers was also observed in both experiments.
