Individual items were rated as +3 (much more satisfied) to -3 (much less satisfied). Higher the score, greater the improvement in satisfaction with each aspect of treatment and lower the score, greater the deterioration in satisfaction with each aspect of treatment. Data was reported for each treatment satisfaction item based on (Item 1=satisfaction with current treatment, Item 2=level of HIV control based on treatment, Item 3=any side effects of present treatment, Item 4=demands made by current treatment, Item 5=convenience in finding treatment, Item 6=flexibility in finding treatment, Item 7=understanding HIV, Item 8=extent to which the treatment fits in with lifestyle, Item 9=recommendation of present treatment to someone else, Item 10=continuation with present form of treatment, Item 11=easy or difficult treatment, Item 12=amount of discomfort/pain involved with present form of treatment).	Up to Week 16
Number of Participants With Their Treatment Preference as Assessed Using Preference Questionnaire for CAB LA + RPV LA Q8W Arm	A preference questionnaire was used to assess participant's preference for the thigh injections compared with the gluteal injections. The "Preference" questionnaire included a single item question evaluating preference of HIV treatment. Participants were required to provide their response to Question, which stated "Which injection site do you prefer". The responses included Injections in the buttock, Injections in the thigh and No preference.	Up to Study Week 24
