I will do questionnaire validity testing and reliability analysis in spss

Need questionnaire validity testing and reliability analysis in IBM SPSS? I help students, researchers and professionals assess survey instruments and understand the findings.

My SPSS work focuses on Cronbach's alpha, internal consistency, corrected item-total correlations, alpha-if-item-deleted diagnostics and exploratory factor analysis (EFA).

Basic: reliability and item diagnostics for up to 20 questions/100 responses.

Standard: Basic plus sampling adequacy checks, EFA, factor loadings and validity findings for up to 40 questions/300 responses, where suitable.

Premium: Standard plus a full instrument review and publication-ready summary for up to 60 questions/600 responses.

Receive organised SPSS output, formatted tables and clear interpretation to guide item decisions. EFA depends on sample adequacy; Cronbach's alpha alone does not establish validity.

Provide your coded dataset, questionnaire, construct names and scoring instructions. Message me first about multiple constructs or reverse-coded items.

Ethical research support only: no fabricated data, manipulated results or guaranteed reliability, validity or publication. You remain responsible for your academic work.
