In Thai-language manuscripts, when English words or phrases are used within the text, the journal generally requires Title Case to ensure consistency and uniformity throughout the manuscript. However, technical terms, statistical symbols, names of statistical methods, or expressions that have specific internationally accepted conventions should retain their standard form or follow the journal's style, and do not need to be converted to Title Case.

English words or phrases appearing in Thai-language manuscripts should capitalize the first letter of major words, including nouns, pronouns, verbs, adjectives, and adverbs.

Articles, conjunctions, and prepositions, such as a, an, the, and, or, but, in, on, of, for, to, should generally be written in lowercase, unless they appear as the first word of a phrase or title.

Examples
Health Literacy
Social Cognitive Theory
Functional Health Literacy
Interactive Health Literacy
Behavior Change Mechanism
Non-Random Allocation
Randomized Controlled Trial

Technical terms, statistical symbols, names of statistical methods, or expressions with specific conventions or internationally accepted forms should retain their established format or follow the style specified by the journal. They should not be converted to Title Case solely for consistency with the general rule above.

Examples of forms that should be retained
Independent t-test
Dependent t-test
Welch's t-test
Cronbach's alpha
p < 0.05
df = 58

For statistical reporting in JMNPR, p, df, and t should be presented in regular type, without italics or bold formatting, in the main text, tables, and accompanying descriptions, to maintain a consistent reporting style throughout the manuscript.

Examples
p < 0.05
p = 0.016
df = 58
Independent t-test
Dependent t-test
Welch's t-test

Use Title Case

Health Literacy
Social Support
Self-Efficacy
Self-Regulation
Vicarious Learning
Total Cholesterol
Two-Way Repeated Measures ANOVA
Group × Time Interaction
Partial Eta-Squared

Retain the Established or Journal-Specified Format

Independent t-test
Dependent t-test
Welch's t-test
Cronbach's alpha
p < 0.001
df = 29

Authors should ensure that English terms are presented consistently throughout the manuscript. Title Case should generally be used for English words or phrases, while technical terms, statistical symbols, or names of statistical methods with established conventions should retain their standard forms. The same style should be applied consistently in the main text, tables, figures, and accompanying descriptions throughout the manuscript.

Note: An English word or expression should not automatically be considered incorrect simply because it does not begin with a capital letter. If the term, symbol, or expression has an established academic or internationally accepted convention, the established format or the style specified by JMNPR should take precedence.
