1. Understanding the Case Study Method in Psychology | 理解心理学中的案例研究法
A case study is an in-depth, idiographic investigation of a single individual, group or event. Unlike experiments that manipulate variables to establish cause and effect, the case study method gathers rich, qualitative data through multiple sources such as interviews, observations, diaries and psychological tests. Within Eduqas GCSE Psychology, case studies are especially relevant to the study of psychological problems, providing a holistic view of how biological, psychological and social factors intertwine in a person's lived experience. Researchers adopt this approach when they want to understand a phenomenon in its full context, often exploring rare or unique conditions that would be impossible to replicate in a laboratory.
案例研究是一种针对单一个体、群体或事件的深入、特殊性取向的研究方法。与通过操纵变量来确立因果关系的实验不同，案例研究法通过访谈、观察、日记和心理测验等多种来源收集丰富的质性数据。在 Eduqas GCSE 心理学中，案例研究尤其适用于心理问题的探讨，它能够全方位地呈现生物学、心理学和社会因素如何在个体的真实生活中交织。当研究者希望全面理解某一现象，或探索难以在实验室中重现的罕见且独特状况时，便往往采用这种取向。
2. Introducing the Case: Jamie’s Social Anxiety | 案例介绍：杰米的社交焦虑
To ground our analysis, we will follow the fictional but realistic case of Jamie, a 15-year-old student who has been referred to an educational psychologist due to persistent school avoidance and overwhelming fear of social situations. Jamie describes an intense dread of being judged or humiliated in front of classmates, which leads to trembling, a racing heart and nausea whenever he is asked to speak in class or eat in the canteen. This anxiety has escalated to the point where his attendance has dropped below 50%, and his academic performance is suffering significantly. Teacher reports mention that Jamie is often isolated during breaks, while his parents notice he has stopped inviting friends over and spends most of his free time alone in his bedroom. The case study aims to build a detailed picture of Jamie's experience to guide future support.
为了将分析落到实处，我们将跟进一个虚构但贴近现实的案例——15岁的学生杰米。他因持续拒学和极度恐惧社交场合而被转介至教育心理学家。杰米自述，他极其害怕在同学面前被评价或羞辱，每当被要求在课堂上发言或在食堂用餐，他都会出现颤抖、心跳加速和恶心的症状。这种焦虑已严重到他的出勤率降至 50% 以下，学业表现也受到明显影响。教师报告称，杰米在休息时间常常形单影只，而父母也注意到他不再邀请朋友来家里，大部分空闲时间都独自待在卧室。本案例研究旨在绘制杰米体验的全景图，以便为后续支持提供依据。
3. Setting Research Aims and Questions | 设定研究目标和问题
Every rigorous case study begins with clear aims and research questions. In Jamie's situation, the psychologist formulates the aim: 'To explore the psychological, social and biological factors contributing to Jamie's social anxiety and to understand how these factors maintain his avoidance behaviour.' From this, three specific research questions are distilled: (1) What cognitive patterns and automatic thoughts are present when Jamie anticipates or enters social situations? (2) How do family dynamics and peer relationships influence his emotional responses? (3) What physiological symptoms does Jamie experience, and how do they correlate with his anxiety triggers? These questions guide the selection of methods and ensure the investigation remains focused and purposeful.
每一例严谨的案例研究都始于清晰的目标与研究问题。在杰米的案例中，心理学家拟定了如下目标：“探究造成杰米社交焦虑的心理、社会及生物学因素，并理解这些因素如何维持其回避行为。”由此提炼出三个具体的研究问题：（1）当杰米预期或进入社交情境时，存在哪些认知模式和自动化思维？（2）家庭互动和同伴关系如何影响他的情绪反应？（3）杰米经历了哪些生理症状，它们与其焦虑诱因之间有何关联？这些问题指引着研究方法的选择，确保整个探究聚焦而富有目的性。
4. Selecting Methods: Interviews and Observation | 选择方法：访谈与观察
To gather deep, contextualised data, the psychologist chooses a combination of semi-structured interviews and naturalistic observation. The semi-structured interview allows flexibility; a set of guiding questions is prepared, but the researcher can probe interesting responses, giving Jamie space to articulate feelings in his own words. In parallel, naturalistic observation is conducted in the school setting during break times and a selected lesson, where an observer notes Jamie's body language, social initiations and proximity to peers. These observations are overt, meaning Jamie and his teachers know the purpose, but the observer remains as unobtrusive as possible. By using more than one method—a technique known as methodological triangulation—the study strengthens the credibility of the final interpretation.
为了收集深层次的、情境化的资料，心理学家选择了半结构化访谈与自然观察相结合的方式。半结构化访谈具有灵活性；研究者会准备一组引导性问题，但也可以对有趣的回答进行追问，让杰米有空间用自己的语言表达感受。与此同时，自然观察在学校的课间休息和一堂选定课程中进行，观察者会记录杰米的肢体语言、主动社交的情况以及与同伴的距离。这些观察是公开的，即杰米和老师们知晓其目的，但观察者尽量保持不引人注目。通过运用多种方法——即方法论三角验证——这一研究增强了最终解释的可信度。
5. Sampling and the Individual Participant | 取样与个体参与者
Case studies rely on purposive sampling; the participant is chosen precisely because they present characteristics relevant to the research focus. Jamie is an opportunity sample in the sense that he has been referred, yet his suitability is confirmed after an initial screening. Importantly, the case study extends beyond a single voice. To capture multiple perspectives, the psychologist also interviews Jamie's mother, his form tutor and a close peer who was once part of his friendship circle. These additional sources provide a richer, more balanced narrative, guarding against reliance on Jamie's self-report alone. The sample size remains very small because the goal is depth, not breadth.
案例研究依赖目的性取样；参与者正是因其具备与研究焦点相关的特征而被选中。杰米属于机会样本，因为他经由转介而来，而其适合性在初步筛查后得到确认。需要强调的是，案例研究并非只听取单一声音。为了捕捉多重视角，心理学家还访谈了杰米的母亲、他的班级导师以及一位曾属于他朋友圈的亲密同伴。这些额外来源提供了更丰富、更均衡的叙述，避免了仅依赖杰米自我报告的风险。由于目标是深度而非广度，样本规模始终非常小。
6. Ethical Safeguards in Practice | 实践中的伦理保障
Working closely with a vulnerable adolescent demands rigorous ethical care. Before any data collection begins, the psychologist obtains fully informed consent from both Jamie and his parents. A detailed information sheet explains the purpose of the case study, the procedures involved, and the potential emotional risks of discussing sensitive topics. Confidentiality is assured through the use of a pseudonym and the secure storage of all audio recordings and transcripts. Jamie is reminded throughout that he has the right to withdraw from the study at any point without penalty, and that he can decline to answer any question. At the end of each session, the psychologist conducts a debrief and provides contact details for additional mental health support, ensuring Jamie's wellbeing remains the highest priority.
与脆弱的青少年密切合作需要严格的伦理关怀。在任何数据采集开始之前，心理学家首先获得了杰米及其父母充分知情的同意。一份详尽的信息手册解释了案例研究的目的、涉及的程序以及探讨敏感话题可能带来的情绪风险。研究者承诺通过使用化名和安全存储所有录音及转录文本来确保保密性。整个过程不断向杰米强调，他有权随时无惩罚地退出研究，也有权拒绝回答任何问题。每次会谈结束时，心理学家都会进行事后情况说明，并提供额外的心理健康支持联络方式，确保杰米的福祉始终是最高准则。
7. Triangulation: Combining Sources for Validity | 三角验证：结合多源数据确保效度
No single data source can tell the whole story. The psychologist applies data triangulation by comparing information from the interviews with Jamie, his mother, the teacher and the peer, and cross-referencing these with the observation notes and Jamie's school attendance records. For instance, Jamie claims that 'everyone laughs at me,' yet the teacher reports no such incidents and the peer confirms that classmates mostly respect Jamie's quietness. This convergence, or occasionally divergence, of evidence highlights the complexity of lived experience and reduces the risk of researcher bias because no single account dominates the narrative. Triangulation therefore raises the overall internal validity of the case study, making the conclusions more trustworthy.
没有任何单一数据来源能够讲述完整的故事。心理学家通过比较杰米、其母亲、教师和同伴访谈中获取的信息，再交叉比对观察笔记与杰米的出勤记录，实施了数据三角验证。例如，杰米声称“每个人都在取笑我”，但教师报告未发现此类事件，同伴也证实同学们大多尊重杰米的安静性格。这些证据的汇聚，有时则是分歧，凸显了生活体验的复杂性，并降低了研究者偏差的风险，因为不再有任何单方面陈述独占叙述。因此，三角验证提升了案例研究的整体内部效度，使结论更为可信。
8. Thematic Analysis of Qualitative Data | 质性数据的主题分析
Once the interviews are transcribed and the observation logs completed, the psychologist undertakes thematic analysis, a widely used method for identifying patterns in qualitative material. The process involves repeated reading of all texts, generating initial codes such as 'fear of humiliation', 'racing heart', 'parental overprotection' and 'social isolation'. These codes are then grouped into higher-order themes. The four dominant themes that emerge for Jamie are: (1) Catastrophic Thinking – anticipating the worst possible outcome in any social encounter; (2) Physiological Arousal – intense bodily symptoms that accompany anxiety; (3) Avoidance and Safety Behaviours – staying at home, not making eye contact, wearing earphones to signal unavailability; (4) Perceived Social Rejection – a persistent belief that others view him negatively. The researcher then writes a coherent narrative that integrates these themes with direct quotations to preserve Jamie's voice.
在访谈转录和观察记录完成后，心理学家着手进行主题分析，这是一种广泛用于识别质性材料模式的常用方法。其过程包括反复通读所有文本，生成初始编码，例如“害怕羞辱”、“心跳加速”、“父母过度保护”和“社交孤立”。随后这些编码被归类为更高阶的主题。浮现出的四个主导主题是：（1）灾难化思维——预期任何社交接触都会导致最坏结果；（2）生理唤醒——伴随焦虑的强烈躯体症状；（3）回避与安全行为——待在家中、避免眼神接触、戴耳机以示意不愿交流；（4）感知到的社会排斥——持续认为他人对自己持有负面看法。研究者随后撰写连贯的叙述，并将这些主题与直接引用语融合，以保留杰米本人的声音。
9. Linking Findings to Psychological Theories | 将发现与心理学理论联系起来
The real power of a case study lies in its ability to connect individual experience to broader psychological theory. Jamie's catastrophic thinking aligns closely with the cognitive model of social anxiety, particularly the work of Clark and Wells (1995), which suggests that socially anxious individuals hold exaggerated negative beliefs about how they appear to others and engage in post-event rumination. The avoidance behaviours fit the operant conditioning principle of negative reinforcement: by staying away from feared situations, Jamie temporarily reduces his anxiety, making the avoidance more likely to recur. The physiological arousal theme supports the biological explanation that heritable temperament and an overactive sympathetic nervous system may predispose some people to intense stress responses. Finally, the perceived social rejection theme echoes sociocultural explanations that emphasise peer group acceptance and the impact of bullying or exclusion during adolescence. By weaving these threads together, the case study demonstrates how multiple perspectives jointly explain Jamie's difficulties.
案例研究的真正力量在于能够将个体经验与更宏观的心理学理论联系起来。杰米的灾难化思维与社交焦虑的认知模型高度吻合，尤其是 Clark 和 Wells（1995）的研究，该研究指出社交焦虑者会对自己在他人眼中的形象持有夸大的负面信念，并陷入事后反刍。回避行为则符合操作性条件反射中的负强化原理：通过远离畏惧情境，杰米暂时降低了焦虑，从而使回避行为更可能再次发生。生理唤醒主题支持了生物学解释，即可遗传的气质与过度活跃的交感神经系统可能使某些人更容易产生强烈的应激反应。而感知到的社会排斥主题则呼应了强调同伴接纳和青春期欺凌或排挤影响的社会文化解释。通过将这些线索交织在一起，案例研究展示了如何用多重视角来共同解释杰米的困境。
10. Evaluation: Strengths and Limitations of the Case Study | 评估：案例研究的优势与局限性
No research method is perfect, and evaluating both strengths and weaknesses is a core skill in Eduqas Psychology. Strengths of this case study include the richness and depth of data obtained, which offers a holistic understanding no laboratory experiment could achieve. It generates hypotheses for future research, for example, about the role of specific safety behaviours in maintaining anxiety. The use of triangulation strengthens internal validity and allows the researcher to check the consistency of information. However, there are clear limitations. The idiographic nature means findings cannot be generalised to all adolescents with social anxiety; Jamie's story is unique. Despite triangulation, the interpretation inevitably involves researcher subjectivity and potential bias. The retrospective element in interviews introduces memory distortion, and the small sample makes replication difficult. These limitations do not invalidate the research but must be transparently acknowledged when drawing conclusions.
没有哪类研究方法可以尽善尽美，评估优势与局限是 Eduqas 心理学的核心技能之一。这一案例研究的优势在于所获数据的丰富性与深度，它提供了一种任何实验室实验都无法实现的全方位理解。研究为未来探索提出了假设，例如特定安全行为对维持焦虑的作用。三角验证的使用强化了内部效度，并使研究者能够检查信息的一致性。然而，也存在着明显的局限性。取向的特殊性意味着发现无法推广至所有具有社交焦虑的青少年；杰米的故事是独一无二的。尽管使用了三角验证，解读过程中仍不可避免地存在研究者主观性与潜在偏见。访谈中的回顾性元素会引入记忆偏差，小样本也导致难以重复验证。这些局限性并不会使研究失去价值，但在得出结论时必须予以透明地承认。
11. Applying the Findings: Suggesting Interventions | 应用发现：提出干预建议
An impactful case study does not finish at interpretation; it translates findings into actionable recommendations. Based on Jamie's profile, the psychologist proposes a multi-component intervention. Cognitive Behavioural Therapy (CBT) is recommended to challenge and restructure catastrophic thoughts, using techniques such as thought records and behavioural experiments. Graded exposure, a core CBT technique, would help Jamie confront social situations step by step, starting with small challenges like greeting a familiar peer and gradually working up to group activities. The psychologist also suggests a school-based mentoring programme to rebuild a sense of belonging and suggests that Jamie's parents attend family sessions to modify patterns of overprotection that may inadvertently reinforce avoidance. These suggestions show how case studies can directly inform person-centred care, bridging the gap between research and real-world support.
一份具有影响力的案例研究并不会止步于解释，它还将发现转化为可操作的建议。基于杰米的个案画像，心理学家提出了多成分干预方案。首先推荐使用认知行为疗法来挑战并重构灾难化思维，应用思维记录和行为实验等技术。作为认知行为疗法的核心技术，分级暴露将帮助杰米逐步面对社交情境，从较小的挑战开始，如向一位熟悉的同伴打招呼，再逐渐过渡到小组活动。心理学家还建议采取学校导师计划以重建归属感，并提议杰米的父母参加家庭会谈，以改变可能无意中强化回避行为的过度保护模式。这些建议展示了案例研究如何直接为以人为中心的关怀提供依据，从而弥合研究与现实支持之间的鸿沟。
12. Exam-style Practice with Model Answers | 考试风格练习与参考答案
Question 1: Outline two methods a psychologist could use to gather data in a case study of social anxiety. (4 marks)
Model answer: One method is a semi-structured interview, which allows the psychologist to ask open-ended questions about the participant's thoughts and feelings, while still having the flexibility to follow up on unexpected but important points (e.g., exploring a particular trigger for a panic attack). Another method is naturalistic observation in the school setting, where the psychologist systematically records the participant's social behaviour, such as eye contact and proximity to others, without interfering. Both methods produce qualitative data that capture the depth of the individual's experience.
问题1：请简述心理学家可在社交焦虑案例研究中使用的两种数据采集方法。（4分）
参考答案：一种方法是半结构化访谈，它允许心理学家询问关于参与者思维和感受的开放式问题，同时还能灵活地对意外却重要的信息进行追问（例如，探索引发惊恐发作的特定诱因）。另一种方法是在学校场景中的自然观察，心理学家在其中系统地记录参与者的社交行为，如眼神接触和与他人的亲近程度，并且不做干预。这两种方法均产生质性数据，能够捕捉个体体验的深度。
Question 2: Discuss one strength and one weakness of using a case study to investigate social anxiety. (6 marks)
Model answer: A major strength is the richness of the data collected. Because the case study gathers information from multiple sources (interviews, observations, records), it provides a holistic picture of how social anxiety influences every aspect of a person's life, something quantitative methods like questionnaires could not fully capture. This depth is valuable for generating new hypotheses. However, a significant weakness is poor generalisability. Since the case study focuses on a single individual, we cannot assume that the findings apply to other young people, even if they share a diagnosis of social anxiety. Each person's experience is shaped by a unique combination of factors, so broad conclusions cannot be drawn with confidence.
问题2：讨论使用案例研究法探究社交焦虑的一个优势和一个弱点。（6分）
参考答案：一个主要的优势在于所收集数据的丰富性。由于案例研究从多种来源（访谈、观察、记录）中采集信息，它能够全方位地呈现社交焦虑如何影响一个人生活的每个方面，而这正是问卷这类量化方法难以完全捕捉到的。这种深度对于形成新的假设极具价值。然而，一个显著的弱点是可推广性较差。由于案例研究集中于单个个体，我们不能假设这些发现也适用于其他年轻人，即使他们也同样被诊断为社交焦虑。每个人的经历都由一系列独一无二的因素所塑造，因而无法充满信心地得出普遍性结论。
