BEHAVIORAL CONTROL OF MEDICINE COMPLIANCE

This study examined the effectiveness of several behavioral techniques on compliance of college students taking vitamin C on q.i.d. regimen. Compliance was assessed by a new technique using a variation of the urine tracer procedure designed specifically for this study. Subjects were provided vitamin C tablets, with three tablets per week containing phenazopyridine, a drug that produces a bright red-orange urine discoloration. Subjects were requested to indicate when urine discolorations occurred, and compliance was assessed by comparing the time of their report to the time predicted on the basis of the scheduled sequence of vitamin C and phenazopyridine tablets. Baseline compliance was assessed for 72 subjects over a three-week period, with the 40 most noncompliant subjects randomly assigned to four groups for Treatment I. The groups were: self-monitoring, taste, taste and self-monitoring, and a no-treatment control group. The self-monitoring procedure involved recording the time medicine was taken; the taste procedure involved providing the subjects with flavored tablets to increase the saliency of tablet taking; and the self-monitoring and taste procedure involved providing subjects with flavored tablets and asking them to record the flavor of each tablet they ingested. At the end of six weeks, half the subjects in each of these groups participated in response-cost procedures while the remaining subjects continued with their previous procedures. Response-cost procedures were implemented by returning a portion of the subjects' deposit only if a preset compliance criterion was met. Treatment II procedures were implemented for an additional three weeks. Results indicated the self-monitoring and taste plus self-monitoring procedures were superior during Treatment I. The implementation of response cost during Treatment II was associated with a marked improvement in compliance, independent of the history of noncompliance. The effects of the taste plus self-monitoring procedure were maintained during Treatment II and results obtained by this procedure were not significantly different from effects of response cost.     

THE USE OF SELF-MODELING TO IMPROVE THE SWIMMING PERFORMANCE OF SPINA BIFIDA CHILDREN

The use of edited videotape replay (which showed only “positive” behaviors) to improve the water skills of three spina bifida children, aged 5 to 10 years was examined. A multiple baseline across subjects design was used, and behavioral changes were observed to occur in close association with intervention. One child was given successive reapplications of videotaped self-modeling with continuing improvements. It appears that a useful practical technique has been developed.     

Age-related Assessment of Postural Control Development: A Cross-sectional Study in Children and Adolescents

Abstract

The aim of this study was to outline an age-dependent range of posturography measures obtained from healthy children. One hundred and fifty healthy 4–18-year-old children underwent video Head Impulse Test and static posturography testing. Surface, length and power spectra values were compared between each group of pupils and 32 healthy adults. As well as a significant (p?<?0.025) increase in surface and length, when compared to healthy adults, increased values within the low/middle frequency domain and within the high frequency domain were also observed in 4–13 and 4–7-year-old children, respectively. In conclusion, although the nature of postural control development remains largely undetermined, this study represents a first attempt to outline an age-dependent normal range of the relative contribution of inputs in typically developing children.

THE EFFECTS OF VIDEO MODELING ON STAFF IMPLEMENTATION OF A PROBLEM‐SOLVING INTERVENTION WITH ADULTS WITH DEVELOPMENTAL DISABILITIES

We investigated the effects of video modeling on the percentage of correctly implemented problem‐solving steps by staff in a group home for adults with developmental disabilities, using a nonconcurrent multiple baseline design across participants. The treatment consisted of staff watching a video model demonstrating the correct implementation of a problem‐solving intervention (i.e., teaching clients to identify problems, possible solutions, and consequences to each solution, and to choose the best solution). The percentage of correctly implemented problem‐solving steps increased for all participants, and the effect was maintained over time, generalized to novel problems, and generalized from role play with a researcher to actual clients.     

Training student teachers to reposition infants frequently

We evaluated the effects of an intervention designed to increase the variety of positions experienced by infants in a child-care setting. Six student teachers were trained, using a multicomponent intervention, to reposition infants according to a chart. The intervention was successful in increasing the mean percentage of correct position changes made by all 6 student teachers, and performance gains by 3 student teachers persisted when supervisor feedback was briefly removed.     

“The interviewer is a machine!” Investigating the effects of conventional and technology-mediated interview methods on interviewee reactions and behavior

Despite the growing number of organizations interested in the use of asynchronous video interviews (AVIs), little is known about its impact on interviewee reactions and behavior. We randomly assigned participants (N = 299) from two different countries (Switzerland and India) to a face-to-face interview, an avatar-based video interview (with an avatar as a virtual recruiter), or a text-based video interview (with written questions) and collected data on a set of self-rated and observer-rated criteria. Overall, we found that whereas participants reported more negative reactions towards the two asynchronous interviews, observer ratings revealed similar performance across the three interviews and lower stress levels in the two AVIs. These findings suggest that despite technology-mediated interview methods still not being well-accepted, interviewees are not at a disadvantage when these methods are used in terms of how well interviewees perform and how stressed they appear to external observers. Implications are discussed.     

The effect of justified video game violence on aggressive behavior and moderated immersion: An experimental approach

The effect of violent video games on aggressive behavior is an important topic in the field of game research. Recently, growing evidence suggests that justified game violence decreases feelings of guilt caused by in-game immoral behavior. However, little is known about the impact on aggressive behavior, and whether other factors moderate this effect. In a two-factor experiment, we tested the impact of justification of video game violence on aggressive behavior, and whether this effect would be enhanced by game immersion. Pilot experiment 1 (N = 60) and pilot experiment 2 (N = 40) demonstrated that the justification of violence and game immersion was successfully controlled by avatar and graphics quality. In the Main experiment, 123 participants played one of four conditions of a video game (2 [justification: justified vs. unjustified violence] × 2 [immersion: high vs. low immersion]) and it was found that participants who played in the justified violence condition reported greater aggressive behavior than those in the unjustified violence condition. In addition, participants who played in high immersion reported greater aggressive behavior than those in low immersion. However, game immersion did not moderate the effects of justified violence. This unexpected effect is likely due to participants' distancing themselves from and identifying less with their violent avatars.     

Development and content validity of a screening instrument for gaming addiction in adolescents: The Gaming Addiction Identification Test (GAIT)

This study describes the development of a screening tool for gaming addiction in adolescents – the Gaming Addiction Identification Test (GAIT). Its development was based on the research literature on gaming and addiction. An expert panel comprising professional raters (n = 7), experiential adolescent raters (n = 10), and parent raters (n = 10) estimated the content validity of each item (I‐CVI) as well as of the whole scale (S‐CVI/Ave), and participated in a cognitive interview about the GAIT scale. The mean scores for both I‐CVI and S‐CVI/Ave ranged between 0.97 and 0.99 compared with the lowest recommended I‐CVI value of 0.78 and the S‐CVI/Ave value of 0.90. There were no sex differences and no differences between expert groups regarding ratings in content validity. No differences in the overall evaluation of the scale emerged in the cognitive interviews. Our conclusions were that GAIT showed good content validity in capturing gaming addiction. The GAIT needs further investigation into its psychometric properties of construct validity (convergent and divergent validity) and criterion‐related validity, as well as its reliability in both clinical settings and in community settings with adolescents.
