The appropriate use of language in context depends on the speaker's pragmatic language competencies. A coding system was used to develop a specific and adult-focused self-administered questionnaire to adults who stutter and adults who do not stutter, The Assessment of Language Use in Social Contexts for Adults, with three categories: precursors, basic exchanges, and extended literal/non-literal discourse. This paper presents the content validity, item analysis, reliability coefficients and evidences of construct validity of the instrument. Content validity analysis was based on a two-stage process: first, 11 pragmatic questionnaires were assessed to identify items that probe each pragmatic competency and to create the first version of the instrument; second, items were assessed qualitatively by an expert panel composed by adults who stutter and controls, and quantitatively and qualitatively by an expert panel composed by clinicians. A pilot study was conducted with five adults who stutter and five controls to analyse items and calculate reliability. Construct validity evidences were obtained using the hypothesized relationships method and factor analysis with 28 adults who stutter and 28 controls. Concerning content validity, the questionnaires assessed up to 13 pragmatic competencies. Qualitative and quantitative analysis revealed ambiguities in items construction. Disagreement between experts was solved through item modification. The pilot study showed that the instrument presented internal consistency and temporal stability. Significant differences between adults who stutter and controls and different response profiles revealed the instrument's underlying construct. The instrument is reliable and presented evidences of construct validity.
在特定情境中语言的恰当使用取决于说话者的语用语言能力。使用一种编码系统为口吃的成年人和不口吃的成年人开发了一份专门针对成年人的自我管理问卷，即《成人社会情境中语言使用评估》，该问卷分为三类：前体、基本交流以及扩展的字面/非字面话语。本文介绍了该工具的内容效度、项目分析、信度系数以及结构效度的证据。内容效度分析基于两个阶段的过程：首先，评估11份语用问卷，以确定探测每种语用能力的项目，并创建该工具的第一版；其次，由口吃成年人和对照组组成的专家小组对项目进行定性评估，由临床医生组成的专家小组对项目进行定量和定性评估。对5名口吃成年人和5名对照组进行了一项试点研究，以分析项目并计算信度。使用假设关系法和因子分析，对28名口吃成年人和28名对照组进行分析，获得了结构效度的证据。关于内容效度，问卷评估了多达13种语用能力。定性和定量分析揭示了项目构建中的模糊性。通过修改项目解决了专家之间的分歧。试点研究表明，该工具具有内部一致性和时间稳定性。口吃成年人与对照组之间的显著差异以及不同的反应模式揭示了该工具的潜在结构。该工具可靠，并呈现了结构效度的证据。
