Primary Outcome Measures

Name	Time	Method
Change from pre-intervention (week 1) at post-intervention (week 10) on the Smartphone Addiction Scale -Short Version (SAS-SV).	Post-intervention (week 10)	This measures smartphone addiction producing a score between 10 and 60, with higher scores indicating greater levels of addiction.

Secondary Outcome Measures

Name	Time	Method
Change from pre-intervention (week 1) at follow-up (week 18) on the Multicultural Quality of Life Index.	Follow-up (week 18)	This measures of quality of life, producing a score between 1 and 10, with higher scores indicating greater quality of life.
Change in daily subjective units of distress from the baseline period (weeks 0 and 1) to the follow-up period (weeks 17 to 18)	Follow-up period (weeks 17 to 18)	Single case analysis will compare daily subject units of distress ratings from the baseline period to the follow-up period. Separate daily ratings, on a 0 to 100 scale, will be obtained for each of anxiety, stress, low mood, and tiredness, with higher ratings indicating higher levels.
Change in daily phone use from the baseline period (weeks 0 and 1) to the intervention period (weeks 2 to 9)	Intervention period (weeks 2 to 9)	Single case analysis will compare daily phone use from the baseline period to the intervention period. Daily use will be measured by screentime (in minutes) and number of pick-ups.
