Interventional
Description of intervention(s) / exposure
This trial has three intervention groups (CBT + Exercise, CBT + Diet, CBT + Exercise + Diet), and two phases (10-week intervention-phase and 5-month follow-up phase). This is psycho-physical intervention in the form of cognitive behavior therapy, exercise regimen and diet plan for obesity and associated factors management. The selected associated factors of obesity are eating behavior, sedentary behavior, body image, and self-control.

The “CBT + Exercise” intervention consists of cognitive behavior therapy (regarding obesity reduction & associated factors management) and exercise (supervised & unsupervised-home based activities). Intervention provided as a group form, participants received 10 consultations (face to face) with a clinical psychologist (weekly sessions, 70-min average time duration for 10-week intervention) for providing awareness and psychological empowerment to participants for regulating exercise in daily life routine, reducing sedentary behavior (by breakdown long sitting period, and short bouts of walking), improving body image (by focusing body parts and accepted changes, as well as trying to reduce abdomen and lower trunk) and increasing self-control (by discontinuing lazy life routine and tailoring exercise according schedule on daily basis). Further, the same “CBT + Exercise” intervention provided 10 consultations (face to face) with a physiotherapist (weekly sessions, 50-min average time duration for 10-week intervention). During consultation physiotherapist offered supervised physical exercise execution (by aerobic exercise 20min & treadmill 20min) and guided unsupervised home-based physical activities (aerobic dancing, jogging, walking; physical activity time 15-35 min goal; pedometer steps 2500-8000 goal). The repeated assessment takes place from week 1(baseline), 4, 8, and week 10th (post-intervention) as an active intervention phase, and final assessment takes place at 30th week as a 5-month follow-up phase. All assessment and sessions occurred in fitness club for all groups but in different timings and days.

The “CBT + Diet” intervention consists of cognitive behavior therapy (regarding obesity reduction & associated factors management) and diet management (restriction of calories, fat, & carbohydrates intake). Intervention provided as a group form, participants received 10 consultations (face to face) with a clinical psychologist (weekly sessions, 70-min average time duration for 10-week intervention) for providing awareness and psychological empowerment to participants for regulating eating behavior (by regulating eating pattern including timing and frequency, avoid overeating, consciously eating slow and maintained normal eating behavior), reducing sedentary behavior (by breakdown long sitting period but avoid additional exercise until trial completion), improving body image (by focusing body parts and accepted changes, as well as trying to reduce abdomen and lower trunk through dieting) and increasing self-control (by controlling eating behavior). Further, the same “CBT + Diet” intervention provided 10 consultations (face to face) with a dietitian (weekly sessions, 40-min average time duration for 10-week intervention). During consultation dietitian offered diet plan (calories 2200-1200 kcal, fat 50-25 gm, and carbohydrate 250-140 gm intakes goal) according body weight and educated participants regarding balanced diet (proper diet, different diet groups, food labels, energy balanced model, calories calculator). The repeated assessment takes place from week 1(baseline), 4, 8, and week 10th (post-intervention) as an active intervention phase, and final assessment takes place at 30th week as a 5-month follow-up phase.

The “CBT + Exercise + Diet” intervention consists of cognitive behavior therapy (regarding obesity reduction & associated factors management), exercise (supervised & unsupervised-home based activities), and diet management (restriction of calories, fat, & carbohydrates intake). Intervention provided as a group form, participants received 10 consultations (face to face) with a clinical psychologist (weekly sessions, 90-min average time duration for 10-week intervention) for the same purpose that described above for the “CBT + Exercise” intervention and “CBT + Diet” intervention. Further, the same “CBT + Exercise + Diet” intervention provided 10 consultations (face to face) with a physiotherapist (weekly sessions, 50-min average time duration for 10-week intervention). During consultation physiotherapist offered the same services that provided for “CBT + Exercise” intervention that discussed above. Furthermore, the same “CBT + Exercise + Diet” intervention provided 10 consultations (face to face) with a dietitian (weekly sessions, 40-min average time duration for 10-week intervention). During consultation dietitian offered the same services that provided for “CBT + Diet” intervention that discussed above. The repeated assessment takes place from week 1 (baseline), 4, 8, and week 10th (post-intervention) as an active intervention phase, and final assessment takes place at 30th week as a 5-month follow-up phase. Intervention fidelity maintained by monitoring self-report diaries on weekly basis and through continuous assessment as well as providing professional experts consultations on weekly bases (face to face).

Comparator / control treatment
The control group consists of knowledge evaluation (reasons for obesity) and awareness sessions or information only (regarding physical activity, diet, eating behavior, sedentary behavior, body image, & self-control). Participants received 10 consultations (face to face, group form) with a clinical psychologist (weekly sessions, 70-min average time duration for 10-week education) for providing information-only about importance of physical activity, reasons for overweight and obesity, advantages and disadvantages of sedentary behavior, balanced diet, energy expenditure and eating behavior, life style modification and body image importance, as well as advantages and disadvantages of self-control. Participants instructed to maintain normal daily life routine activities until current program sessions finished. Repeated assessment takes place from week 1(baseline), 4, 8, and week 10th (post-intervention) as an active intervention phase, and final assessment takes place at 30th week as a 5-month follow-up phase.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Conceal allocation is made through online permuted random block sizes randomization by a researcher, but not involved in participant recruitment process and assessment. The team members whom recruited potential participants according eligibility criteria were unaware, when this decision was made, to which group the participant were allocated.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We applied permuted block randomization through online (www.randomization.com) random permuted blocks of different sizes. A randomization plan generated on the basis of I.D number by a person not involved in recruitment process as well as recruitment team and participant not aware which i.d number allocated to which group.

Statistical methods / analysis
The data were analyzed in eighth key steps:
1. In the first step, preliminary analysis run for computing data normality distribution and outcomes measures differences between and within groups through boxplot.
2. In the second step basic assumptions were evaluated and satisfied before run the repeated measures ANOVA such as there was no missing data, sampling distribution was normal, homogeneity of variance and sphericity were satisfactory, as well as absence of outliers. After that primary analyses were run for computing baseline differences in primary measures (body weight, body mass index, waist-to-hip ratio, percent body fat) of all groups. Repeated measures ANOVA run for computing effect of treatment condition and time in primary measures among groups from baseline to post intervention and follow-up phase..
3. Post-hoc analyses were run to confirm the significance differences among groups.
4. In the fourth step, primary analyses were run for computing baseline differences in self-reported measures (physical activity time, pedometer steps, calories, fat, and carbohydrates intakes). Independent sample t-test was run to compute baseline differences in self-reported measures between groups according treatment conditions. Repeated measures ANOVA run for computing effect of treatment condition and time in self-monitor measures among groups from baseline to post intervention and follow-up phase.
5. In the fifth step, secondary analyses were run for computing baseline differences in associated factors (eating behavior, sedentary behavior, body image, and self-control) among groups. Repeated measures ANOVA run for computing effect of treatment condition and time in contributing factors among groups from baseline to post intervention and follow-up phase.
.
6. In the sixth step, descriptive statistics were run including mean, standard deviation and frequency distribution to compute differences of cognitive behavior therapy (CBT) effectiveness questionnaire among groups.
7. In the seventh step, one-way ANOVA run for computing CBT effectiveness differences among groups at baseline. Repeated measure ANOVA was run to compute changes in CBT effectiveness from baseline to end of treatment.
8. In the eighth final step, Pearson correlation was run for computing relationship among obesity diagnostic components (body weight, body mass index, waist-to-hip ratio, percent body fat) and obesity associated factors (eating behavior, sedentary behavior, body image, and self-control) at baseline and end of treatment.

Summary
Brief summary
The current study aims to measure effectiveness of psychological plus physical interventions for obesity and associated factors. The psycho-physical interventions are combinations of cognitive behavior therapy (CBT) plus exercise plus diet management to reduce obesity diagnostic factors such as body weight, body mass index (BMI), waist-to-hip ratio (WHR), and percent body fat (PBF) among women. The same intervention targeted obesity associated factors such as eating behavior, sedentary behavior, body image, and self-control. Through a randomized control trial repeated measure design, the current study recruited one-hundred and twenty-eight females (N=128) from South Punjab, Pakistan by employing penal data technique with purposive sampling on the basis of inclusion criteria (BMI>25 kg/m2). The sample distributed into four equal groups through online permuted block randomization. The experimental group-1 (CBT + Exercise) received 10-week sessions of cognitive behavior therapy along with exercise execution during intervention phase. Further, the experimental group-2 (CBT + Diet) received 10-week sessions of cognitive behavior therapy with diet management plan. The next experimental group-3 (CBT + Exercise + Diet) also received 10-week sessions of CBT along with exercise execution and diet plan. The last group-4 (control) attend 10-week sessions but information only. Outcomes were measured at baseline, 4th week, 8th week, and 10th week as an intervention phase, and 30th week as an follow-up phase.
