Thesis (Ph.D.)--The Chinese University of Hong Kong (Hong Kong), 2022.

Health risks of plastic waste burning are substantial. Progressive increase in plastic waste volume in rural villages in China leads to more waste burning, which pose considerable negative health hazards to the villagers. In the literature, interventional studies on improving plastic waste management practices were non-existent. As such, there is an urgent need to add to the literature on behaviour change communication intervention targeting plastic waste burning, in particular by separate collection. The objectives of this thesis are to explore the predictors of villagers' behavioural intention for separate collection of plastic waste (SC), to assess if providing threat-efficacy appeal is more effective (than solely providing communication materials and simple instructions) in increasing the practice of SC, and to explain the reasons for households to practise and not to practise SC.Following the five steps of P-Process, this thesis can be divided by two parts. Part I comprises 60 randomly cross-sectional surveys. Firth logistic regression was used to analyse the predictors for behavioural intention of SC. Results showed family support to take collective action, perceiving SC as not difficult and perceived autonomy in decision making are important predictors, which were useful in persuasive message design. Part II comprises a parallel two-arm, single-blinded randomised controlled trial stratified by two sub-villages, entitled Communication for Plastic WASTE Management Practices (C- 9 PASTE), to assess the effects of door-to-door, interpersonal persuasion using threat efficacy appeal together with communication material and health education pamphlets (intervention group) over the usual practice with only material and pamphlets (control group). 70 households were recruited and 68 households were followed-up at 7-month interval. Repeated measures analysis of covariance revealed statistical non-significance in the number of plastic items separately collected in the Blue Bin, F(1,65) = 0.069, p=0.79 between intervention and control group at post-intervention, post-reinforcement and 7- month follow-up, taking baseline as covariate. As for the weight of the plastic items, a similar pattern of non-significance was noted, F(1,65)=0.033, p=0.86. The results may suggest that using interpersonal persuasion by threat-efficacy appeal did not differ from distributing materials with simple instructions and reminders to bring about SC. As such, a simple form of interpersonal communication, i.e. brief instructions on the use and maintenance of the Blue Bin and periodic reminders, together with health education pamphlets and the Blue Bin, may suffice to elicit the practice of separate collection of plastic waste. Subsequent to the conduct of C-PASTE, an explanatory sequential multiple case study of 10 cases was conducted to facilitate further explanations of the trial results with multiple sources of data framed under social practice theory. Results were analysed by framework analysis in form of case summary matrix alongside pattern matching and cross-case synthesis. Results indicated that "practitioners" are those who had continuous use with the Blue Bin (material), positive connotations with the use of the Bin/the practice (meaning) and know-how (competence); and suggested that as long as the three elements are functionally present, the absence of a strategic, tailored interpersonal persuasion would not affect the elicitation of the desired behaviour.To our understanding, C-PASTE was the first-of-its-kind interventional research in SC for Dong ethnic group in rural Guizhou. The trial data added to the literature on the effects of using interpersonal persuasion with threat-efficacy appeal to conduct behaviour change communication trial in rural contexts, particularly villages undergoing agrarian transition. In addition, framing an intervention as a social practice may guide the planning of future health promotion effort in rural contexts.

520 $a 焚燒塑膠垃圾的健康風險是極為顯著的。在中國農村裏，不斷增多的塑膠垃圾量便需要更多的垃圾焚燒，繼而對村民的健康帶來危害。在公共衞生文獻中，有關改善塑膠垃圾處理的慣常做法干預研究並不常見。有鑑於此，我們有迫切需要豐富有關文獻，特別是關於針對焚燒塑膠垃圾，並以分開收集塑膠垃圾方式進行的行為改變溝通的干預研究。而本文的目標有三：第一，探討影響村民分開收集塑膠垃圾行為意圖的預測因素；第二，評估威嚇及效能訴求方式對於提升分開收集塑膠垃圾行為的效果是否比只分發物資和簡單指示為佳；第三，闡明為何某些家庭實踐或不實踐分開收集塑膠垃圾的原因。跟根據 P-Process模型的五步曲，本文分為兩部分。第一部分是一個 60份的隨機橫切面式問卷調查。透過 Firth 的邏輯回歸來分析影響村民分開收集塑膠垃圾行為意圖的預測因素，結果發現全家支持並願意集體行動、認為分開收集不太困難、以及認為有自主決定權為重要的預測因素。這有助設計具說服力的健康訊息。第二部分是一個平行、雙臂、單盲、上下寨分層的隨機對照試驗，簡稱 CPASTE，以評估逐家逐戶、以威嚇及效能訴求方式人際說服，配合物資和健康教育單張（干預組）及只分發物資的慣常做法與簡單指示（對照組）的效果。本試驗招募共 70戶家庭，其中有 68戶能在 7 個月後成功回訪。協方差分析指出兩組在三次量度中藍桶內的塑膠垃圾數量 [F(1,65) = 0.069, p=0.79] 和重量 [F(1,65)=0.033, p=0.86] 在統計學上沒有顯著差別（以基線作為協方差）。結果提示以威嚇及效能訴求方式人際說服與簡單指示的功效並無差別。因此，透過配合物資和健康教育單張的簡化版人際說服（使用和保養藍桶的簡單指示及定期提醒），可能已經足夠引出分開收集塑膠垃圾的行為效果。在回訪後，C-PASTE 通過社會實踐理論框架進行了由十個個案組成、解釋式序列設計的多重個案研究，以不同來源的數據協助進一步解釋隨機對照試驗的結果。多重個案研究法的結果透過框架分析，以摘要矩陣、模式比對及個案交叉 12 綜合分析展示。結果顯示實踐者的特徵包括持續使用藍桶（物資），對於藍桶或實行上有正面印象（意義），以及知道如何實踐（能力）。另外，數據表示假若該三個元素同時存在及運作，即使沒有度身訂做和策略性的人際說服也不影響實踐分開收集塑膠垃圾的行為。據我們了解，C-PASTE 是第一個在貴州侗族農村進行的干預性試驗研究。隨機對照試驗數據能豐富有關在鄉村場景下(特別是農業轉型的村莊) 運用人際說服，特別以威嚇及效能訴求方式進行行為改變溝通方面試驗的文獻。除此之外，以社會實踐角度來訂定干預框架能協助策劃未來農村環境中的健康促進項目。.
