Theory of Planned Behavior-Based Digital Addiction and Screen Time Management Training for Teachers

18 juni 2026 bijgewerkt door: Belkıs CAN, Aydin Adnan Menderes University

The Impact of a Planned Behavior Theory-Based Digital Addiction and Screen Time Management Training on Teachers' Internet Addiction, Sleep Quality, and Psychological Well-being

This thesis focuses on problematic internet use, a widespread issue in contemporary society, and its negative effects on sleep quality and psychological well-being. The indispensable role of the internet in daily life and the risks associated with excessive use constitute an important area of research, particularly in relation to internalizing symptoms and health-related problems. Within this context, considering teachers' intensive engagement with digital media and their role as role models, the study aims to improve their awareness and behaviors regarding digital media use.

The aim of the thesis is to examine the effects of a Theory of Planned Behavior (TPB)-based Digital Addiction and Screen Time Management training program on levels of internet addiction, sleep quality, and psychological well-being among middle school teachers in Aydın province, using a randomized controlled experimental design.

In terms of methodology, a total of 102 teachers-51 in the intervention group and 51 in the control group-will be assessed before and after the training. Data will be collected using a Personal Information Form, the Young Internet Addiction Test-Short Form, the Pittsburgh Sleep Quality Index, and the Psychological Well-Being Scale.

The expected outcomes are that the implemented training will significantly reduce teachers' levels of internet addiction, improve their sleep quality, and lead to improvements in psychological well-being. These findings are expected to contribute to teachers' health and to provide guidance for the development of similar intervention programs for other populations.

Tijdsspanne
Personal Information Form
Tijdsspanne: Baseline, immediately after intervention, 3 month after intervention.
The form, prepared by the researchers, consists of 9 questions created in line with the literature review, covering general information about the teachers' socio-demographic characteristics.

Tijdsspanne
Young Internet Addiction Test-Short Form
Tijdsspanne: Baseline, immediately after intervention, 3 month after intervention.
The scale was originally developed by Young, and its short form was later created by Pawlikowski, Altstötter-Gleich, and Brand. The scale is a 12-item, unidimensional, 5-point Likert-type scale (scored from 1 to 5). The Turkish adaptation of the scale was carried out by Kutlu and colleagues. The total score ranges from 12 to 60, with no reverse-coded items or cut-off point. Higher scores on the scale indicate a higher level of internet addiction in the individual. While the Cronbach's Alpha internal consistency coefficient of the YIAT-SF scale was 0.85, this value was calculated as 0.89 in this study.

Tijdsspanne
Pittsburgh Sleep Quality Index (PSQI)
Tijdsspanne: Baseline, immediately after intervention, 3 month after intervention.
Developed by Buysse et al. (1989), PSQI measures sleep quality/problems over the past month. Cronbach's alpha = 0.80; validity confirmed via test-retest. Turkish adaptation by Ağargün et al. (1996) also showed α = 0.80, confirming psychometric stability. Total 24 items: 19 self-reported, 5 based on spouse/roommate observations (clinical use only; roommate item excluded from scoring). Scoring uses 18 items across 7 components, each item 0-3. Total score 0-21; ≥5 = clinically significant. Components: Subjective Sleep Quality (item 6), Sleep Latency (items 2+5a), Sleep Duration (item 4), Sleep Efficiency (items 1+3+4), Sleep Disturbances (5b-5j), Medication Use (item 7), Daytime Dysfunction (items 8+9). Item 4 is used for both Sleep Duration and Sleep Efficiency, a key design feature.
Baseline, immediately after intervention, 3 month after intervention.
Psychological Well-Being Scale
Tijdsspanne: Baseline, immediately after intervention, 3 month after intervention.
Diener and colleagues (2009) developed a measurement tool to assess individuals' socio-psychological health status (Diener et al., 2010). This scale was later adapted to Turkish culture by Telef (2013) and transformed into an 8-item form (Telef et al., 2013). In the analyses conducted, the factor loadings of the scale items were found to range between 0.54 and 0.76. As a result of the reliability analyses of the scale, the Cronbach's alpha coefficient was calculated as 0.80. It was determined that the item-total correlation coefficients ranged between 0.41 and 0.63, and the t-test results were statistically significant (p < 0.001). The response options used in the scale have a seven-point Likert-type structure: "Strongly disagree," "Disagree," "Slightly disagree," "Undecided," "Slightly agree," "Agree," and "Strongly agree.
