A 6-minute engaging video will be shown, illustrating examples where a mother initially withholds her appreciation for her son's effort in school and later express it. The video will also capture the effect on the child and the family. Attributional discussion questions will follow to elicit positive outcomes of expressing appreciation and the negative outcomes of withholding appreciation (e.g., What may be the long-term effects of showing appreciation on your child, family, or on yourself?). Key points will be summarised and reinforced to enhance behavioural intention (Schwarzer & Luszczynska, 2008). Then the participants will be asked to plan by indicating when (e.g., Saturday afternoon), what (e.g., child helping a younger sibling prepare for a dictation test), and how (e.g., "I can see that you gave up your leisure time to help your sister with the spelling. Thank you!") they would express appreciation to their children.

Participants will watch a 6-minute video showing examples of a father criticising his son, which will be replaced by positive communication later, and the different reactions evoked in the child and the family. Then, participants will have an attributional discussion on the negative effects of criticism (e.g., negative effect on self-worth and motivation) and positive outcomes of using constructive feedback (e.g., promptly identifying undesirable behaviours without relating to personal traits or abilities). In small groups, they will work out alternatives (i.e., constructive feedback; termed "positive reminder" in the intervention) to criticism, and each plan and write down when (e.g., after school), what (e.g., low test marks), and how (e.g., "How do you prepare for the tests?)

This workshop will emphasise the importance of consuming at least 5 portions of fruit and vegetable daily for a healthy diet, and aim to boost participants' self-efficacy in achieving this. Participants will be presented with examples of one portion of fruit or vegetable, and then create their own recipes. They will also consider how to overcome obstacles of consuming more portions. Each participant will set goals and write down plans on when, where, what, and how they would increase their fruit and vegetable intake of their children and family as a whole.

Being assessed by averaging two items, measuring the frequency with which parents expressed appreciation (express appreciation towards children's efforts; express appreciation towards children's strengths) in the past 7 days. Responses range from 0 to 6 (0: '0 time,' 1: 'one to two times per week,' 2: 'three to four times per week,' 3: 'five to six times per week,' 4: 'once a day,' 5: 'two to three times a day,' and 6: 'four times or more per day'). The Cronbach's alpha is 0.90.

Being assessed by averaging two items, measuring the frequency with which parents expressed criticism (criticise children; express dissatisfaction towards children's behavior) in the past 7 days. Responses range from 0 to 6 (0: '0 time,' 1: 'one to two times per week,' 2: 'three to four times per week,' 3: 'five to six times per week,' 4: 'once a day,' 5: 'two to three times a day,' and 6: 'four times or more per day'). The Cronbach's alpha is 0.93.

Being assessed by summing two items, one each for the number of servings of fruits and vegetables consumed in the past week.

Measured by averaging three items, "If I express my appreciation through words or action more often, my children will be more positive to themselves", "If I express my appreciation through words or action more often, my children will appreciate the other family members more", "If I express my appreciation through words or action more often, my family will be happier and more harmonious". Participants rated their agreement using a 10-point scale (1 = totally disagree, 10 = totally agree).
