Poor medication adherence (MA) among Type 2 Diabetes Mellitus (T2DM) patients had found to be gnarly and devastating (Krass et al 2015; Sharma et al 2014). It was estimated that more than half of the patients failed to achieve recommended glycaemic goals due to nonadherence (GarcÃa-Pérez 2013; World Health Organization 2003). Furthermore, greater adherence rate was significantly associated with better glycemic control, fewer hospital visits and admissions, and lower medical costs. On the other hand, lower adherence rate was significantly associated with poor medication tolerance, the frequency of medication intake (> 2 times a day), having concomitant depression and negative belief about the medications. Consequently, patients who poorly adhere to medications would take more medications due to the poor glycemic control and development of micro- and macrovascular complications (American Diabetes Association 2013). Such condition would further worsen their adherence due to more complex medications and a greater chance of experiencing drug-related side effects (GarcÃa-Pérez 2013). This inevitably increases the economic burden and wastage to the healthcare system (Meng et al 2017). Hence breaking the vicious cycle is an urgent call to all stakeholders.
Notably, Ministry of Health Malaysia (MOH) had initiated several interventions in curbing the MA problems at national level. One of those which has been perpetuated and led by pharmacists is "Know Your Medicine" (KYM) Campaign since 2007. The national KYM campaign aims to promote the quality use of medicines through mass communication and group-based approach. The messages conveyed include information on their medication management such as why, how and when to take medicines, reporting adverse drug events, awareness on the rational use of medicines and medications that need special precautions. In specific, assuring and improving medication adherence among patients is one of the important components of the campaign (PSD 2008).
In term of improving medication adherence among Malay T2DM patients, a structured group-based intervention (SGBI) called "Know Your Medicine - Take It For Health" with abbreviation KYM-TIGF, was created by the researchers of this study who work at Sarawak Pharmaceutical Services Division in 2016 under the KYM campaign. The KYM-TIGF is a theoretical based, patient empowerment, culturally appropriate and a combination of psychosocial, educational and behavioral intervention. It is a one-off SGBI that aims to improve the medication adherence through the message specially designed with a cross-theoretical framework as recommended by Slater (1999). The model to measure the effectiveness of the SGBI is an integrated model with Theory of Planned Behaviour (Ajzen 1991) as main theory and Information-Motivation-Behavioural Skills Model (Fisher et al. 2006) as supporting theory. The primary outcome of this study is the HbA1c. The secondary outcomes of this study are the medication adherence level as well as the psychosocial variables of the integrated model which include attitude to medication adhere, the subjective norm to medication adherence, perceived behavioral control towards medication adherence, adherence information, adherence skill and intention to adhere.
A current systematic review by Odgers-Jewell et al (2017) revealed that little had been done to investigate the effectiveness of group based education in improving medication adherence among T2DM patients. This concur with the comprehensive review on interventions to improve medication adherence by Conn & Ruppar (2017), as the researchers conclude that there is an urgent need in evaluating the interventions to improve medication adherence that employs group-based approach.
The evidence on the effectiveness of the KYM-TIFH in promoting medication adherence among T2DM patients remain lacking. Furthermore, the current measurement on the effectiveness of the campaign is the increment of the awareness level of public towards proper use of medicines (PSD 2013) without measuring the impact of the campaign on actual behavior change.
Besides aforementioned, Malay ethnic was found to be the main contributor to the prevalence of poor MA (PSD 2013) due to forgetfulness (75.3%) and reluctant to take prescribed medications (43.8%). Facing the high prevalence of poor MA among Malay patients, an effective and efficient approach which could engage more patients within a shorter period of times to improve the medication adherence problems is highly preferred (Odgers-Jewell 2017). Hence, all the problem statements addressed above lead to the necessity of conducting this study, which aims to investigate the effectiveness of the SGBI "KYM-TIFH" in improving MA among Malay patients with T2DM.
Based on the problems stated above, this study aims (1) to measure the effectiveness of MEDIHEALTH in improving the medication adherence level and the component of the extended TPB, (2) to identify the component of the extended TPB that predicts medication adherence after participating in MEDIHEALTH, and (3) to investigate the sustainability of the program.
Based on the first specific objective, ten hypotheses are to be tested:
H1a: Increase in intention to adhere would be mediated by improvements in attitude towards adherence after baseline, which is achieved by participating in MEDIHEALTH.
H1b: Increase in intention to adhere would be mediated by improvements in subjective norm towards adherence after baseline, which is achieved by participating in MEDIHEALTH.
H1c: Increase in medication adherence would be mediated by improvements in intention to adhere after baseline, which is achieved by participating in MEDIHEALTH.
H1d: Increase in intention to adhere would be mediated by improvements in perceived behavioural control towards adherence after baseline, which is achieved by participating in MEDIHEALTH.
H1e: Increase in intention to adhere would be mediated by improvements in adherence information after baseline, which is achieved by participating in MEDIHEALTH.
H1f: Before the intervention, there are no significant differences of medication adherence level and the psychosocial variables related to it among the participants between the intervention group and the control group.
H1g: After 3, 6 and 12 months of the program, the medication adherence levels among the participants in the intervention group are significantly greater than the medication adherence levels before the intervention.
H1h: After 3, 6 and 12 months of the program, the medication adherence levels among the participants in the intervention group are significantly greater than the medication adherence levels of the participants in the control group.
H1i: After 3, 6 and 12 months of the program, the HbA1c levels among the participants in the intervention group are significantly greater than the HbA1c before the intervention.
H1j: After 3, 6 and 12 months of the program, the HbA1c levels among the participants in the intervention group are significantly greater than the HbA1c levels of the participants in the control group.
For the second specific objective, eight hypotheses are to be tested:
H2a: Improvement in attitude towards adherence will contribute to the increase in intention to adhere.
H2b: Improvement in subjective norm towards adherence will contribute to the increase in intention to adhere.
H2c: Improvement in perceived behavioural control towards adherence will contribute to the increase in intention to adhere.
H2d: Improvement in perceived behavioural control towards adherence will contribute to the increase in medication adherence.
H2e: Improvement in intention to adhere will contribute to the increase in medication adherence.
H2f: Improvement in adherence information will contribute to the increase in perceived behavioural control towards adherence.
H2g: Improvement in adherence information will contribute to the increase in medication adherence.
H2i: Improvement in medication adherence level will contribute to the decrease in HbA1c level.

| Intervention Group | Experimental | All the participants who are randomly assigned to the intervention group will be undergoing the Know Your Medicine-Take it for Health (KYM-TIFH) program, which is a one-off structured group-based intervention (SGBI). |
|
| Control Group | No Intervention | All the participants who are randomly assigned to the control group will not be given any information related to KYM-TIFH. However, they will be assigned to the venue for the control group and will be asked to fill in questionnaires with the assistance of four facilitators. A briefing on how to answer the questionnaire will be given by the main facilitator and all facilitators are allowed to answer any questions raised by respondents related to the questionnaire. However, they are not allowed to answer on behalf of the respondents. After the completion of the questionnaire, they will be informed about the subsequent follow-up measurement after three, six and twelve months. After that, they will be dismissed and having usual care provided by the health clinic as before without any changes. |

| Know Your Medicine - Take It For Health (KYM-TIFH) | Behavioral | The KYM-TIFH employed psychosocial, educational and behavioral approach. It was designed based on the application of multiple behavior change theories and persuasion theory as recommended by Slater (1999). The cross-theoretical framework for the message design of intervention as recommended by Slater (1999) involved theories such as Transtheoretical Model (TTM) (Prochaska & Velicer 1997), Theory of Reasoned Action (TRA) (Ajzen & Fishbein 1980), Protection Motivation Theory (PMT) (Rogers 1975), Elaboration-Likelihood Model (ELM) (Petty and Cacioppo 1986) and Social Cognitive Theory (SCT) (Bandura 1992) as in Table 2. Nonetheless, the intervention embraces the philosophy of patients' empowerment, which had found to be effective in engaging patients to produce behavioral change among diabetes patients (Anderson 1995; Anderson et al 1995). Hence, the facilitators are trained to employ a non-didactic approach in facilitating the and eliciting the learning among the group members. |
