A modelagem de equações estruturais com estimação por mínimos quadrados parciais (PLS-SEM) tem sido empregada nas mais variadas áreas de pesquisa, aumentando a quantidade de artigos publicados com o uso desse método de modo exponencial. Há vários motivos para que isso esteja ocorrendo, mas um deles é o fato do software SmartPLS ter facilitado o uso do PLS-SEM. Este artigo tem o objetivo de apresentar sete exemplos didáticos com conjuntos de dados reais e disponíveis àqueles que queiram aprender ou ensinar PLS-SEM, tratando de temas como: avaliação do modelo de mensuração, avaliação do modelo estrutural, multicolinearidade, variável latente de segunda ordem, mediação, moderação com variável numérica e categórica (MGA – multi-group analysis).

Purpose
This paper aims to present the fundamental aspects for the development and validation (D&V) of attitudes' measurement scale, as well as its practical aspects that are not deeply explored in books and manuals. These aspects are the results of a long experience of the authors and arduous learning with errors and mistakes.


Design/methodology/approach
The nature of this paper is methodological and can be very useful for an initial reading on the theme that it rests. This paper presents four D&V stages: literature review or interviews with experts; theoretical or face validation; semantic validation or validation with possible respondents; and statistical validation.


Findings
This is a methodological paper, and its main finding is the usefulness for researchers.


Research limitations/implications
The main implication of this paper is to support researchers on the process of D&V of measurement scales.


Practical implications
Became a step-by-step guide to researchers on the D&V of measurement scales.


Social implications
Support researchers on their data collection and analysis.


Originality/value
This is a practical guide, with tips from seasoned scholars to help researchers on the D&V of measurement scales.

Purpose
The purpose of this paper is to analyze the perception of the influence of greenwashing and of attitudes and beliefs in the decisions of purchase of green products in the retail.


Design/methodology/approach
A quantitative research was carried out by means of a survey with a sample of 880 consumers living in São Paulo city, Brazil, who buy in supermarkets weekly or biweekly.


Findings
It was possible to evaluate a model that analyzed the aspects that greenwashing carries and the aspects that the attitudes and beliefs of the consumer present. As a result, it is inferred that when greenwashing is identified in the product, it loses the aspects of loyalty, satisfaction and benefits, as well as becoming a product that causes confusion of consumption. Further, consumer attitudes and beliefs show that they are guided by the aspects of perceived loyalty, satisfaction and benefits and that the perceived risk aspect is practically ignored.


Originality/value
The originality of this study is in evaluating consumer perception focusing on several aspects of purchase intention simultaneously, considering perception and behavior of consumer before greenwashing and green consumption and using all aspects together (satisfaction, loyalty, subjective and control forces, risk and benefits perception). Besides complementing with other determinants like consumer attitudes and beliefs, confusion of green consumption, behavior controlled in relation to green consumption and greenwashing. Thus, it contributes with an interdisciplinary study whose scale and methodology can be used by analogous studies.
