Participants assigned to the intervention group will receive both will receive usual care (standard clinical and medical services) provided to individual with CKD stages 3-4 who attend the CKD clinic at medical outpatient department on their clinic follow up , and a 12- weeks self-management intervention delivered by two dedicated and trained renal nurse educators. The intervention will involve three group-based sessions, CKD booklet and three follow-up phone calls.

Participants randomized to the control group in this study will receive usual care (standard clinical and medical services) provided to individual with CKD stages 3-4 who attend the CKD clinic at medical outpatient department on their clinic follow up. Usual care consisted of brief verbal information (2-5 minutes) about taking medications, reducing salt, smoking cessation and reducing alcohol consumption. There will no structured program but only the provision of written material to patients.

Group-based sessions will be scheduled at week two, week four and week six. Participant will be given a printed booklet Participants will receive three individual follow-up phone calls of 20-30 minutes each at week three, week five and week seven.

kidney disease knowledge will be measured using a self-report instrument Kidney Disease Knowledge Survey (KiKS). It includes 28 questions, 5 multiple choice type questions and 23 Yes-No questions; none of the questions included an "I don´t know" option. To assess the survey score, 1 point was given to each correct answer and zero to each wrong one. The questionnaire doesn't have domains, and the total score was calculated as the sum of the correct responses to each question divided by the total number of questions, which results in values from 0 to 1 where 1 means the highest level of knowledge.

CKD self-management behavior will be assessed by Self-report instrument Chronic Kidney Disease Self-management (CKD-SM) by (C. C. Lin et al., 2013). CKD-SM instrument contains of 29-item to measure participants' self-management behavior factors. Each item is scored on a Likert scale from 1-4 with 1 being 'never' and 4 'always'. Total scores of the CKD-SM range from 29 to 116 and higher scores indicate better self-management behavior in managing CKD.

Self-efficacy will be measured by using a self-report instrument the Stanford Self-Efficacy for Managing Chronic Disease - 6-item Scale. This widely used six-item instrument was derived from several self-efficacy scales developed and tested for the Chronic Disease Self-Management study by Lorig et al., 2001. Each item is scored on a 10-point Likert scale ranging from "not at all confident" (1) to "totally confident" (10), with a total score ranging from 6-60. The scale is scored by calculating the mean of at least four of the six items, therefore allowing for a maximum of two missing items. A higher number indicates a higher self-efficacy.
