“…To study the influence of the activities on the evaluation of acoustic comfort, some questionnaire surveys were also conducted at the case site (Yu and Kang 2009). The questionnaire survey was conducted immediately after behaviour measurement, and every questionnaire survey was generally done by the interviewer in 3-5 minutes (Litwin 1995). In terms of subjective investigation, 1223 valid questionnaires were obtained at the survey site.…”

Human activities are important to landscape design and urban planning; however, the effect of sound-related activities on human behaviours and acoustic comfort has not been considered. The objective of this study is to explore how human behaviours and acoustic comfort in urban open spaces can be changed by sound-related activities. On-site measurements were performed at a case study site in Harbin, China, and an acoustic comfort survey was simultaneously conducted. In terms of effect of sound activities on human behaviours, music-related activities caused 5.1-21.5% of persons who pass by the area to stand and watch the activity, while there was a little effect on the number of persons who performed excises during the activity. Human activities generally have little effect on the behaviour of pedestrians when only 1 to 3 persons are involved in the activities, while a deep effect on the behaviour of pedestrians is noted when more than 6 persons are involved in the activities. In terms of effect of activities on acoustic comfort, music-related activities can increase the sound level from 10.8 to 16.4 dBA, while human activities such RS and PC can increase the sound level from 9.6 to 12.8 dBA; however, they lead to very different acoustic comfort. The acoustic comfort of persons can differ with activities, for example the acoustic comfort of persons who stand watch can increase by music-related activities, while the acoustic comfort of persons who sit and watch can decrease by human sound-related activities. Some sound-related activities can show opposite trend of acoustic comfort between visitors and citizens. Persons with higher income prefer music sound-related activities, while those with lower income prefer human sound-related activities.

“…Thus, not only must measurement be reliable but also free of systematic, uncontrolled bias that could be caused by a variable Z that is irrelevant by hypothesis. There are several types of validity (see again Litwin, 1995). Economists often distinguish between internal and external validity.…”

“…The instrument was pilot tested with 6-8 th students (n = 34) and revised (Shilts, Townsend, & Horowitz, 2002). Seventh and 8 th grade students (n = 46) completed the revised instrument on two occasions, three weeks apart, with no intervention (Litwin, 1995). Reliability coefficients were 0.73 for dietary behavior items, 0.55 for physical activity behavior items, 0.59 for dietary self-efficacy items and .48 for physical activity self-efficacy items.…”

Abstract:The efficacy of a youth development intervention on improving eating and physical activity(PA) self-efficacy, goal attainment scaling, goal effort, and behaviors was examined in a repeated measures, quasi-experimental field trial. Ethnically diverse students (n=64) from a low-income middle school participated in the 10-session intervention driven by the Social Cognitive Theory with a Goal Setting Theory emphasis. Participants, 13-14 years old, made significant changes in dietary behaviors (P=0.03) and PA selfefficacy (P=0.02) after receiving the intervention. Self-efficacy did not mediate dietary behavior change but did mediate the small changes made in PA. Goal effort was not a mediator of behavior change. After the intervention, more participants rated themselves as making one lasting improvement in eating (P<0.001) and PA (P<0.05) choices and/or were planning on making more. This study adds to a small body of research with youth supporting use of goal setting interventions for diet and PA change in low-income communities.
