Beyond Brainstorming: Exploring Convergence in Teams.

Collaborative brainstorming is often followed by a convergence activity where teams extract the most promising ideas on a useful level of detail from the brainstorming results. Contrary to the wealth of research on electronic brainstorming, there is a dearth of research on convergence. We used experimental methods for an in-depth exploration of two facilitation-based interventions in a convergence activity: attention guidance (focusing participants on procedures to execute a convergence task) and discussion encouragement (engaging participants in conversations to combine knowledge on ideas). Our findings show that both attention guidance and discussion encouragement are correlated with higher convergence quality. We argue that attention guidance's contribution is in its support of coordination, information processing, and goal specification. Similar, we argue that discussion encouragement's contribution is in its stimulation of idea clarification and idea combination. Contrary to past research, our findings further show that satisfaction was higher after convergence than after brainstorming.

Can an evidence-based book club intervention delivered via a tablet computer improve physical activity in middle-aged women?

BACKGROUND: Fewer than 50% of middle-aged women participate in regular physical activity (PA). Innovative approaches that engage women who may not otherwise participate in PA programs are warranted. The purpose of this study was to explore the acceptability and feasibility of a 12-week tablet-based book club for improving middle-aged women's PA. MATERIALS AND METHODS: Thirty women (35-64 years of age) were randomized to the Fit Minded Tablet (n=15) and the Standard Fit Minded (i.e., face-to-face intervention) (n=15) groups. The Fit Minded Tablet was adapted from the Standard Fit Minded, a previously tested, theory-based book club intervention using books as a platform for discussion and group support to help women adopt regular PA. Both interventions met weekly for 3 months, for a total of 12 sessions. Tablet group participants accessed materials (e.g., e-books, workbook, live/recorded videoconferencing) via a tablet computer; Standard group participants received materials (e.g., printed books, workbook, live face-to-face meetings) in person. Feasibility (i.e., implementation and expansion) was assessed using process evaluation, qualitative interviews, satisfaction surveys, and quantitative outcome assessments. RESULTS: Women in the Tablet group attended fewer meetings (mean, 8.25) than women in the Standard group (mean, 9.9). Videoconferencing, digital literacy, and participant engagement limitations were observed in the Tablet group. Tablet participants enjoyed the e-books but thought technology barriers hindered their engagement during meetings. Women in both groups valued the support they received from other group members. Standard participants cited this support as a key contributor to their PA changes, whereas Tablet participants reported needing in-person contact to feel more connected. CONCLUSIONS: Given the popularity of tablet computers and the value that middle-aged women place on group interaction to support their PA behaviors, additional research is warranted to determine best strategies for optimizing social support, mitigating technology barriers, and improving engagement in online and mobile health promotion programs targeting middle-aged women.

A Novel Inexpensive Use of Smartphone Technology for Ecological Momentary Assessment in Middle-Aged Women.

BACKGROUND: Commercially available mobile and Internet technologies present a promising opportunity to feasibly conduct ecological momentary assessment (EMA). The purpose of this study was to describe a novel EMA protocol administered on middle-aged women's smartphones via text messaging and mobile Internet. METHODS: Women (N = 9; mean age = 46.2 ± 8.2 y) received 35 text message prompts to a mobile survey assessing activity, self-worth, and self-efficacy over 14 days. Prompts were scheduled and surveys were administered using commercial, Internet-based programs. Prompting was tailored to each woman's daily wake/sleep schedule. Women concurrently wore a wrist-worn accelerometer. Feasibility was assessed via survey completion, accelerometer wear, participant feedback, and researcher notes. RESULTS: Of 315 prompted surveys, 287 responses were valid (91.1%). Average completion time was 1.52 ± 1.03 minutes. One participant's activity data were excluded due to accelerometer malfunction, resulting in complete data from 8 participants (n = 252 [80.0%] valid observations). Women reported the survey was easily and quickly read/completed. However, most thought the accelerometer was inconvenient. CONCLUSIONS: High completion rates and perceived usability suggest capitalizing on widely available technology and tailoring prompting schedules may optimize EMA in middle-aged women. However, researchers may need to carefully select objective monitors to maintain data validity while limiting participant burden.

Exploring asynchronous brainstorming in large groups: a field comparison of serial and parallel subgroups.

OBJECTIVE: The aim of this study was to compare the results of two different modes of using multiple groups (instead of one large group) to identify problems and develop solutions. BACKGROUND: Many of the complex problems facing organizations today require the use of very large groups or collaborations of groups from multiple organizations. There are many logistical problems associated with the use of such large groups, including the ability to bring everyone together at the same time and location. METHODS: A field study involved two different organizations and compared productivity and satisfaction of group. The approaches included (a) multiple small groups, each completing the entire process from start to end and combining the results at the end (parallel mode); and (b) multiple subgroups, each building on the work provided by previous subgroups (serial mode). RESULTS: Groups using the serial mode produced more elaborations compared with parallel groups, whereas parallel groups produced more unique ideas compared with serial groups. No significant differences were found related to satisfaction with process and outcomes between the two modes. CONCLUSION: Preferred mode depends on the type of task facing the group. Parallel groups are more suited for tasks for which a variety of new ideas are needed, whereas serial groups are best suited when elaboration and in-depth thinking on the solution are required. APPLICATION: Results of this research can guide the development of facilitated sessions of large groups or "teams of teams."
