Different terms describe these phenomena, however there is no standardization within the terminology. This review evaluated the definitions and assessment tools of seven terms – (i) ‘psychotic experiences’; (ii) ‘psychotic-like experiences’; (iii) ‘psychotic-like symptoms’; (iv) ‘attenuated psychotic symptoms’; (v) ‘prodromal psychotic symptoms’; (vi) ‘psychotic symptomatology’; and (vii) ‘psychotic symptoms’. Methods: EMBASE, MEDLINE, and CINAHL were searched during February–March 2019. Inclusion criteria included 1989–2019, full text, human, and English. Papers with no explicit definition or assessment tool, duplicates, conference abstracts, systematic reviews, meta-analyses, or no access were excluded. Results: A total of 2238 papers were identified and of these, 627 were included. Definitions and assessment tools varied, but some trends were found. Psychotic experiences and psychotic-like experiences were transient and mild, found in the general population and those at-risk. Psychotic-like symptoms were subthreshold and among at-risk populations and non-psychotic mental disorders. Attenuated psychotic symptoms were subthreshold but associated with distress, risk, and help-seeking. Prodromal psychotic symptoms referred to the prodrome of psychotic disorders. Psychotic symptomatology included delusions and hallucinations within psychotic disorders. Psychotic symptoms was the broadest term, encompassing a range of populations but most commonly involving hallucinations, delusions, thought disorder, and disorganization. Discussion: A model for conceptualizing the required terms is proposed and future directions needed to advance this field of research are discussed.
